Talk to me about how much space I need per chick. When we grew our first chicks, we only had 6 or 8 at a time. They were only indoors for about 5 weeks, since it was late summer. Dearest husband wants to get 25 broilers at the end of February. I am guessing that they will need to stay indoors for 7-8 weeks. So how much space should I need?
