Brand new to raising chickens, just got 4 chicks on Saturday. We are currently using a large dog crate as a brooder. They have plenty of space now but I'm assuming they'll need more soon(before they're ready to move to the outdoor coop).. I've been looking around and have seen lots of brooder ideas but they all seem to only be for the small newborn phase and I don't see many ideas for the in between phase of not tiny chicks anymore but not fully feathered yet either.. What does everyone do with their chicks at this phase?
