Hello all! I am brand new to backyard chickens and am getting started with my first chickens in the next few weeks. I am planning to start with just 4 baby chicks and see how that goes before diving into the big leagues! I have a few questions, the first being about the brooder. What size does it need to be to keep the chicks in? I plan to keep them in my garage (it is not heated but has power so heat lamps won't be an issue). I also don't want to spend a signficant amount of time/money on the brooder since I don't know if I will be getting more chicks down the road. Any advice, recommendations, or comments? Thank you!
