This year is my second flock, my first ended tradically. We remodeled the coop and put up a huge fence and a avary net. Now my hens are closing in on four months old. I'm about to start changing their feed, but they show no interest in the nesting boxes. At first I wasn't sure what to put in them, so I used just regular hay that I had for my horses. They kicked that out of the boxes. Then while I was at Atwoods getting something and I asked one of the workers what they thought would be the best. He informed me that "chickens nest the crap out of straw", that it keeps them warm. So, I bought straw, once again they just kicked it out and all over the floor. I don't know how to get the to start using their boxes. The way my coop is designed there is a top shelf, 7 feet off the ground and that is what they are roosting on at night. Is there a trick to this? It is really starting to fustrate me, I have a feeling they are just going to lay eggs up on that top shelf which the eggs will just roll off and onto the ground. They are Golden Sex Links.
