I have 29 cornish x coming at the end of the week. I made a 5x3 and was going to cover the sides with deer netting, good or bad? I built it out of 2x2s and some osb for the floor. This is my first attempt at raising chicks. Is the 5x3 brooder big enough for them until they can go outside, around 3 weeks? I will share some pics when I get my chicks.
