I have a hen outside with 4 - 6/7 day old chicks and a baby chick in the incubator with eggs that don;t seem to be hatching yet. Baby chick needed help out of its shell but is doing ok now though not eating or drinking yet. We don;t want to lost it and don't know what to do? It is cold out and so not sure if I should put baby with mum and older chicks?
