My pekin has hatched 3 eggs (4 left) and they seem to be eating a little chick crumb - well they're walking through it anyway. She doesn't seem to be eating it though and is only eating grass which goes straight through her and makes very smelly green poo. She goes mad for corn but then tries to feed it to the chicks - can they eat it? I can't take her away to feed her separately as she goes mad. Have tried mixing the crumb with warm water but she turns her nose up at that too. Also - I took the other 4 eggs away this morning as I thought she'd given up on them and they were cold (had already had to revive one of the chicks she had abandoned), but then noticed a little crack in one this afternoon. Have put them back under her - is there any hope after about 10 hours or is this jeopardising the 3 chicks?
