Getting the idea from the website you referred me to I put Ruby in a wire dog crate that I keep young chicks in until they're ready to go out in the coop. I placed it in a nice spot outdoors in the shade garden where all of her flock mates can stop by to visit. At night, I block the entrance to the nest boxes and let her outside in time to go to bed with the others. Seems to have taken 2 days to break her using this method. I hope I'm not speaking too soon, but she's been out in the yard with the others all morning, and has made no moves toward the nest box.
Thanks for the help!! Now, I have another use for the dog crate, making it more cost effective. Works for me!
