this is my first broody hen and she's been sitting on a clutch of 18. one hatched the other day and thought i heard more chirping under her. but went out this mornin to check and their was a horrendous smell... checked the eggs and no more baby chick. 17 eggs... lots of filthy maggots!! so. i cleaned out that nest box and moved her into the other one with the remaining eggs after i wiped the maggots off. just wondering what's going on!?
