My friend put some chickens on our property about a year ago. Well I got chicken fever and have 42 ten week old chicks. The point is one of his hen's has gone broody.. I have some eggs in the fridge. I would like to put them under her. Do I need to take them out of the fridge to get to room temp before placing under her? She is sitting on 5 eggs. Only one is fertilized. She is in the pen with a batam coshin roo, coshin hen & 3 leghorns. The roo tries to mate with all his girls but I think the coshin is the only one he really gets. My friend has others hens in a pen with fertilized eggs. I am so excited . She by the way is a Wandotte. She has been in the nest all day. Usually I can pick her up or pet her....not today. How many eggs should I put under her.
