She is seperated. She is in the broody coop. I think she may have eaten the egg.Thanks Chickenreferee, I was thinking that maybe removing the cage might make a difference. She thinks of it as the nursery and they are intruding. I think I will give it a try this weekend, slowly one chicken by one chicken.
Marlowmanor, that is why I seperated my broody, I came up with 3 eggs missing in one week, so I moved her to a new enclosed kenel in the coop and got new eggs and started from scratch. The other chickens kept laying in her box and I was having to constantly go thru the eggs to see which were hers. Maybe you could try seperating them?
