Oh, that's fine.No unfortunately I wasn't able to do it gradually due to my work schedule. I had to pull the old one out to get the new one up and although they watched from the yard they came in that night to the new coop. Not ideal but I had no choice. I hope they learn to like it soon. I over worry about my flock!
Either wrangle them in every night for how ever long it takes.......or wrangle them once and leave them in there for 3-4 days and nights.
