fairly new to this, introducing pullets to existing flock for first time. planning on putting the 6-8 week old pullets in the coop next to hens(seperated by wire) for a week then introducing all of them to new coop we built which connects to old coop and grow out pen. built pullet escape door which should only allow pullets back into grow out pen if they need to escape big gals. do you guys think will work without anyone getting too hurt? thanks
