I have read several threads about brooders but most of them are people with chicks in late spring. I plan to use an old dog crate I have for a large dog as a brooder so all of my chicks can be in one brooder instead of two separate ones. Also I will be able to put in sticks for perches and room to spread their wings a bit. The crate is large and The only place I have room for it is either in my living room (which I do not want to do) or in my garage which is unheated. Lately our temps have been in the 20s at night. The garage is insulated and I can easily set a heat lamp (or 2) for them. Will the cold nights be an issue? I also have a barn cat who sleeps in the garage so I would need to put something around the cage so she can't get her paws in there and torment the chicks. Silly cat won't go in the backyard and is oblivious to the already 20 chickens back there. Any suggestions are greatly appreciated.
