My buff orpington (who i thought was a boy but glad shes not) was in the nesting boxes when i came down to check for eggs. I dont know if she has gone broody or laying an egg. She is just sitting there and she picks up peices of shavings and hay and puts them under her. she also puts her head under and moves some things around. I thought this meant she was broody, but i dont have any experience with this sort of thing. Anyway if she is broody, all that is under her are too plastic eggs(the ones u use for easter) and possible one of her own unfertilized eggs. Im ordering some fertile eggs that will be here not this coming friday, but next friday, the 21. can i put a few of these eggs under her? Will it not work because she has already been sitting on some for two weeks? Help!
