Okay I thought I posted this but maybe it was just to the farm discord. But here's my brooder setup! The chicks from both levels are in the bottom while I'm cleaning the top portion.
You can just see on the bottom left of the first photo there's another wire cage for overflow, but it's rarely used. That doubles as the sale cage when I go to swaps. The water has vitamins in it this round, it's not dirty.
Chicks stay in the top portion for the first 2 weeks or so, where they have access to heat. I hatch chicks weekly, so the oldest move down when the new ones hatch, and the middle chicks by that time are usually sleeping on the cold side of the brooder, meaning the new hatch can't go over there and get cold, because there's always bigger birds to snuggle up to.
It also prevents a lot of stress, to have staggered hatches. I used to hear a lot of crying when a new hatch got put into the brooder alone. Now one or two might protest being alive for a few minutes directly after being relocated, but they calm down almost immediately and begin following the older birds around to eat and drink.
The stand is made of 2x4s screwed together. The bottom of the brooder is a Low Boy 50g aquarium that doesn't hold water. The top is 2x2s and 1x2s screwed together and covered in 1/4" hardware cloth. It actually fits snugly over the lowboy and is not attached to anything, so it technically can be removed but it's a massive hassle to do so. The entire front opens and folds down flat, for easy access. The heat lamp (I actually got a new one yesterday) is secured with metal shower curtain rings in several ways from several points, to prevent failure, and plugs directly into the wall. Both top and bottom have an aquarium grow light bar on top for full spectrum lighting.
I really love this setup! It's been very easy to use and clean, and it serves the purpose very well.
Bonus, it looks rad as hell at night
Softly glowing monstrosity.
