So here is a pic of the brooder. It's 4x8 and about a foot high. I have the 4 side doors in it to put food in, and I have 3 more cut out of the top to put water in. There is about a 2x3 foot area cut out of the middle top where the heat lamp is, so if they want heat they go to the center, and if they want to move away, they have the rest of the brooder. The bottomw is 1/4 inch mesh and under the mesh floor is the plywod floor that is catching droppings/food scatter, etc that I can remove and hose down eventually.
Mistakes: I only cut holes on one side, so it's hard to reach dead birds, or rescue birds that are being picked on from the other side. After these birds are out and when I get ready to brood another batch, I will have the same holes cut out on the other side. Other than that, Ive had the birds about a week.....of the 100, I've lost 8 so far.
to everyone who gave me ideas and tips.
