I've been reading about breaking a broody hen. I adopted her after she went broody and the original owner didn't want to deal with her after she hatched a few eggs. I got her 14 months ago, she is ~ 2.5 yrs old and went broody again today. I plan on doing the wire cage method I she continues tomorrow. My question is, do I place a roost in yet or does she sit on the wire cage? How big should the cage be? I have a few different kinds of cages lying around. Thank you!
