My husband and I have built a new large coop for my ladies and we are keeping the smaller coop they're leaving for some chicks that are also in the run now. I still have to protect the chicks from the grown chickens when I'm not out keeping an eye out, so to go ahead and put the new chicks in the old coop and push the grown chickens to use the new coop, I would have to block everyone in their proper places. So my question, is it a good idea to suddenly block the chickens off from the coop and nesting box they've been using? The new coop is ready and I plan to put a couple of wooden eggs in the nesting boxes in the new coop. Any tips and suggestions would be excellent! The grown chickens are all buff orpingtons and there are 4 of them. The chicks are 6 weeks old and have been walking in and out of the old coop already, so I'm sure they'll like it quite a bit. Thanks!
