So I hatched about 40 standard sized mixed chicks about 8-10 weeks ago. We built a big, new chicken house for them alongside our incredibly old and ugly, but useful chicken house--so we designed perches for them using round rods, built a nice long (not steep) ladder for them to use, and hung an infrared bulb at the top of the house. I can't get them to use the perches at all. They are all just hanging out on the floor in the bedding. They have been in their new home for about a week--any tips on encouraging them to roost on the perches.
