I am pretty new at this. My chickens are only 6 months old and have been producing eggs about 3 weeks. My two little Silkies will not leave the nest. They are almost sitting on each other. I don't think they have eaten or had water for the last 3 days. The other 6 chickens and rooster just seem to be ignoring them. Are they OK? Should I put food in front of them? Should I make them leave the coop and lock the door? Thanks for any help you can give.
