Ok, so I had 20 chicks in this - And I knew that it was already tight and that they were gonna out grow it quickly, so I asked my dad if we could build a bigger brooder and he said yes. So I went to youth group and came home to this. I love my daddy. .gif we ran out of the plastic netting stuff so on the left side is just a window screen until we can get to Lowes to get more. the chicks are loving this, they are jumping around and chasing each other every where, I love it. The demsions are 5'L x 4'W x 18"H Here is my baby Lola on her favorite place, sitting on the waterer.
