I have 2 broody hens. One is a large Barred Rock, she was sitting on 8 eggs. 2 hatched fine, then I found 1 wet and dead in the nest, another dead on the coop floor, she then abadoned the other eggs and moved her 2 chicks in a corner. Found 1 or those 2 dead this morning. Moved the Mama and her 1 chick into the garage into a dog crate. My other broody hen is a little banty mix. I saw her go after the 1 little chick with her feathers all flared out and her tail up and making quite a racket at the chick. I think she killed the others. She's sitting on 3 eggs. Is she protecting her nest or is she jealous? Or just a mean hen? Also was wondering if anyone has tried substituting store bought day old chicks under a sitting hen, will she accept them? I thought I might try this. Any suggestions?
