I have 22 11 week old pullets. One of my brown leghorns takes off somewhere and I can't not find her when it is time to go back in the coop. She did twice in the past week and this morning I find her and the cat laying sleeping together in the barn. So, tonight it looks like she took 2 other pullets with her!!! So now 3 of them are missing! I looked everywhere but could not find them. I do let them free range during the day and they were all there at treat time but it seems this little girl takes off when it is time to go in the coop! How can I stop her from doing that, if at all? My roos are upset and won't sleep because they know they are not all there!!!
