At what age should I set up laying boxes in the coop? my 2 oldest hens are 15 weeks, the rest range from 8-10 weeks. When I was building the coop I went ahead and put them in, but all the chicks decided they wanted to play and roost in them, so I took them out. However I did leave the table they go on, and they sit on that a lot. Do I need to move all of it or just build another, less familiar table , and move it to another area of the coop?
