What kind of trays do you use? I'm going to do that for this next hatch, I purchased plastic canvas and I'm going to cut dividers and zip tie them together. I figured with plastic I can sterilize it and re-use them.
I started penciling in my breeding pens for July, a lot all can change still as I don't know who all my girls are or what cockerel is going to mature into the best birds, but I may end up with 6 or 7 different pairings, which actually sounds like a really bad idea

two or three sounds more manageable.
