Hi! Our broody hen MO (7 years old) is sitting on 6 eggs, 3 have hatched 1 is half way out, 1 cheeping and the other quiet. I am concerned about the one that is half hatched. How long before I step in and help it out? Mum seems a bit fidgety so I think she is concerned too. I am not sure whether to leave it over night but would hate to find it dead in its shell in the morning.
Advice please.
