Hi gang, I bought these beautiful EXPENSE sheet metal nest boxes online and hung them about 2 feet off the ground at the back of the hen house. Well, my girls are starting to lay now... YIPPEE....and they don't even look up at these beautiful boxes. They were laying on the ground until I had my hubby build a wooden box and set it on the ground underneath the other boxes. This is where they are laying now. How do I get them to use the elevated boxes or should I just lower them all to ground level? For some reason, I always thought hens like to lay off the ground??
