Hi my name is cole, it is my first time incubating chickens and I am incubating 12 eggs. I made a brooder out of a dog cage with a heat lamp. I hope I get 6-10 babies. Lets say I get 8 baby chicks. How long can they stay is the dog cage brooder before getting too cramped? Or do they stay in there for the whole 8 week breeding process? Thanks for any information you can give me!
