So here is my duplex brooder:
There are 71 one week old chicks in the upper unit and they cover about 25% of the floor space. They decided to be shy for the camera, except one Lav Am up front. Temps in the box range from very cool to warm and cozy and they are free to move around. Just in time, too, as there are 27 more Easter Eggers hatching tomorrow, and I still have about 18 underperformers inside getting a chance to advance without competition, and another 60 turkeys hatching over the next couple of weeks.
Really good work. Those corner braces will hold me and My four sons.
