Your dog carrier seems to be the place they want to lay their eggs. I would put it in their coop. Lately I have some birds that want to lay eggs under their nest boxes. All of my nest boxes are accessible from outside of the coops so that means I have to go in to get the eggs. I put some wire there but they moved the wire and still layed their eggs under the nest box so I put another larger piece of wire under the nest box. Today I'll see if they have moved it. Good luck and have fun...
