I built a Brood Box for my new babies.
I made it fairly large for the number of birds I got.
4' X 8' X 2'.It did not take them long to get to loving it
Actually I got the design from an article here in BYC I just made it larger for the number of birds.
I made mine 4' X 8' X 24"
Made the top out of 2" X 2" X 8'
I was going to cover the top with hardware cloth but found that Chicken Wire was cheaper. It took less than a full roll of 2' X 50' with 1" mesh Chicken Wire to cover the top.
3 Sheets of 15/32" Plywood
13 - 2" X 2" X 8'
and 1 Roll of 2' X 50' Chicken Wire.
Brood Lamp and 250 Watt Heat Bulb
I got 2 rolls of chicken wire for less than 1 roll of hardware cloth.
At night I cover the box with a tarp leaving part of it open for ventilation.
I have the Brood Box on a Word Document and will post it
