i was wondering if I could brood some baby chicks that will be arriving this week in my older girls coop outside? My plan is to have the chicks in a large steel dog crate that we've brooded all our chickens in before, then keep them in there possibly with a heat lamp at night (not sure how to rig that up in the coop without having the other hens try and mess with it, unless the lamp is hung within the dog crate?). I wanted some people's thoughts on this idea, and any tips people have! I've read on here that people keep the chicks separate from the older flock for about 10 weeks until the chicks are bigger, but I was also not sure if I should fence off part of the coop for the chicks once they'be graduated from the crate? I have a chicken tractor that I would put the chicks in during the day once they're out of the brooder, around 5 weeks. Would the tractor be a good way to keep the chicks separate from the flock until the 10 week mark?
