I moved from Tx to AR about six months ago, with five of my chickens. They stopped laying for a while - stress, cold, shorter days - but resumed laying normally (4 eggs/day). About 3 weeks ago, quantity of eggs became sporadic, then one day I found yolk remnants. Then caught a hen carrying a broken egg around the run. Searched the forum, here's my speculation and what I've done so far. Advice on additional steps would be greatly appreciated, I'm getting nowhere... -My RIRed suddenly is laying GIANT eggs with thin shells. I believe one of these eggs broke open, giving one of the girls a chance to develop a taste for egg and now she's eating a couple of eggs a day. Other hens may have observed and joined in, although 2 hens are clearly guarding eggs, which they've never done before. -I tried soap eggs and ceramic eggs to see if I could eliminate the behavior. One soap filled egg was broken open and left laying, one was broken open and dragged into the run and discarded. Now they just toss aside the soap and ceramic eggs, they seem to be able to ID them and throw them into the coop pan out of the nest box. Still only getting 1-2 eggs a day, if that. -Also have been going out to the coop every hour or two to observe/collect eggs but can only say with certainty that one hen is eating eggs. My particulars: -I have 2 Orpingtons, 1 RIRed, 1 Austrolorp, 1 Wyandotte. -They live in a confined run, enclosed on six sides with hardware cloth due to predation here. Run is 20X20, 2 small coops are inside the run, attached as one coop, should hold 8 chickens. -I feed free choice (buffet is always open) layer ration, oyster shell and grit. Daily spinach, berries, cabbage and apple on a string, other goodies but mostly fruits and vegetables. They get a small ration of treats once a day - meal worms, seeds, treat nuggets. Occasionally earthworms. -I've observed most of them eating the calcium but my RIRed loves veggies - she doesn't eat much layer ration, haven't seen her eat calcium and ignores the treat bowl. I'll expand into their large coop and a much larger run but not until next year, when I plan to add chickens. I may have to let the small flock live out their days in the current run and start a new flock in the new run - I think egg eating is contagious. Thanks for your thoughts!
