I am thinking I may do the following. When she is off the nest, i will put eggs and straw in a cutout low box, so low that she won't really notice it but high enough to keep her and the straw and eggs in. Then at night, I will lift this contraption, chicken/eggs/straw and all out of the nestbox and onto the floor of the coop. I think I won't bother with the dog carrier anymore, although I could take the top off and put the cardboard box into it, and then just let her sit on the floor outside of the nestboxes. We can see how that goes. If that won't work, then I'll just let her sit where she wants and hope for the best. Today is day 2 that she is on the eggs fulltime.
