I'm getting 25 chickens from Ideal Poultry this Thursday(hopefully) and I was wondering how big of a brooder I will need? Some general ideas would be great. I already have an XL dog crate and a couple large cardboard boxes that will be rigged up once the chicks start to get bigger, but I wanted to know what others have done for this amount of chicks. Keep in mind they're staying inside for around 8 weeks due to weather, and they'll be in a heated garage, so we have plenty of space. All ideas and advice will be appreciated!
