I have 9 hens of different breeds, all 1 year old, and have been together since 1 day old. One of the Delawares started eating eggs this spring. Just an egg or 2 a week. Now she is addicted and hovers over the others until they lay, and then ambushes the egg. Of course, the others dine with her. I recently re-homed the rooster as he was getting aggressive with me and the hens. The Delaware was pretty high up the pecking order before the rooster left, but now seems like a real bully. She torments the hens when they try to lay, and is a bit aggressive towards me. She won't leave them alone, trying to get underneath them (I"m guessing to get the egg) when they are trying to lay. Yes, I have tried the fake eggs, and they have oyster shell available free choice. They are on 20% protein feed. The other Delaware has gotten aggressive towards the other hens and me, also. I'm assuming the pecking order is being re-established since the ousting of the rooster. He has been gone for about a month. Things were nice and quite at first, but quite stressful now. The nest box was also modified about 2-3 weeks ago to make it a roll away. Tried to keep it mostly the same. A few eggs are laid in the box, but mostly not. Most are laid in the hen house floor or out in the run. Should I isolate Ms egg eater? She isn't hurting the others that I can tell, but just won't let them lay their eggs in peace. Plus, I don't get to eat them I'm hoping to see if the others will eat the eggs if she is not around to crack them open. Can I put a large wire dog cage inside the run for her? Would 36"x 24" be big enough? I know I changed a lot on them at the same time, but this egg eating has to stop. She gets 2-3 a day!
