Why Your Speckled Sussex Stopped Laying: A Diagnostic Flowchart

A hen that was producing a steady brown egg and suddenly gives you nothing is frustrating, but it is rarely a mystery. Most stoppages come from a short list of causes, and you can find yours by asking questions in a sensible order. Think of this as a flowchart in words: answer each question, follow the branch, and stop when you find the likely cause. For background on normal output, see our pieces on realistic egg numbers and the normal reasons hens slow down.

Question 1: Is the Hen Actually Not Laying, or Are the Eggs Going Somewhere Else?

Before you worry about the hen, check the obvious. Hens that have found a hidden nest in the hedge or under the shed will quietly stack up a clutch. Search the range, and look under shrubs and in corners. Egg-eating also looks like a stoppage, since broken shells and sticky nest boxes are the clue. Our extension.org predator guidance notes that missing eggs can be taken by skunks, snakes, rats, opossums, raccoons, jays or crows, so a sudden drop with no shells at all may mean something is stealing them. Collecting eggs daily helps in all these cases. If you have only a few hens, remember that you are probably not tracking each one, so confirm which hens have actually stopped before assuming the entire flock has.

Question 2: How Old Is She?

Production falls with age. A hen is usually at her best in her first laying year and then declines, with the dual-purpose heritage breeds typically holding on longer but at a lower rate than commercial layers. Our article on the four-year laying curve explains what to expect, and it is worth remembering that Speckled Sussex pullets also mature slower than production breeds (see why they mature slower). If she is a young bird not yet in lay, check pullet development and the first egg. If she is old, the answer may simply be age.

Question 3: Is It Molt Season?

Look at the feathers. A hen with feathers on the ground, pin feathers coming in and a ragged appearance is molting, and she will usually stop laying while she rebuilds her plumage because feather growth takes a great deal of protein. Molts typically happen in the fall and can run for weeks. See our molt season survival guide. Keep her on good feed and be patient.

Question 4: How Much Light Is She Getting?

Daylight drives laying. Mississippi State University Extension's guidance on egg-producing hens says that once egg production begins, the total light from natural and artificial sources should not be reduced, and that proper lighting and nutrition help hens produce year-round. Shortening autumn days therefore cause a slowdown for many backyard flocks, and winter is the usual low. Our guide on winter laying covers options. If you add light, do it gradually and with a timer rather than switching on a lamp at random, and think about whether you want to push the birds, since many keepers prefer to let hens rest naturally.

Question 5: Is She Broody?

Go and look at her at night. A hen that sits on the nest day after day, puffs up, growls and pecks you is broody, and broody hens stop laying while they sit. See broodiness in Speckled Sussex and our new article on breaking broodiness humanely.

Question 6: Is Her Diet Right?

A laying hen needs a complete layer feed and a source of calcium. Too many treats dilute the ration, and our 10 percent rule article explains why. The MSD Veterinary Manual's page on management-related problems in backyard poultry links a sudden drop in egg production with fatty liver, which in turn is associated with obesity and a scratch-heavy diet. Speckled Sussex gain weight easily, so this is a real concern: see obesity and egg production. Also check that water is clean and available at all times, as a drop in water intake quickly reduces laying.

Question 7: Has Anything Stressed Her?

Hens are creatures of habit. A predator visit, a new flock member, a change of coop, a dog, loud construction, or extreme heat can all pause production for days or weeks. Heat above about 90 degrees can be hard on a heavy bird (see summer heat management). If a new bird has joined the flock, bullying may be keeping a low-ranking hen off the nest and feed (see reading flock behavior).

Question 8: Is She Sick or Carrying Parasites?

If the hen is also lethargic, thin, has abnormal droppings, a pale comb or breathing noise, then an illness or parasite burden may be responsible. Follow our lethargy checklist, isolate the bird and call a vet. Reproductive problems such as egg binding or an internal laying problem can also stop production; our guide to egg binding and prolapse explains the emergency signs. Parasites are covered in our parasite guide. Do not treat blindly; a vet can run tests, and a diagnosis is better than a guess.

A Quick Summary

1. Rule out hidden nests, egg-eaters and thieves.
2. Consider age.
3. Check for molt.
4. Check the hours of light.
5. Check for broodiness.
6. Review feed, treats, calcium and water.
7. Look for stress.
8. Look for illness or parasites and involve a vet.

Keep a simple log of eggs per day. Even a note on the calendar will show you when a drop began and what changed that week. For more on keeping a flock productive, see farm.fm's food section and the agriculture directory.
