I have 10 chickens, 4 Silver Lace Wyandottes who are 16 weeks old and 6 others who are 12 weeks. They were roosting fine, but a couple weeks ago we put the nesting boxes into the coop, and now the Silver Lace are roosting in the nesting boxes. Every night I put them up on the roost, and now only three of the four are roosting in the boxes. The problem is that they have caught on. Now as soon as I pick one up to put her on the roost, the other two run to the middle of the coop where I can't easily reach them. They could start laying any day now, so I hesitate to cover the nesting boxes, but I don't know what else to do. Any suggestions?
