I have 2x 16 week old wyandotte hens and a 20ish week old sussex who we are trying to integrate with the younger 2 original girls.. They are in a 4x4 coop and a 4x8 run ive been told in another thread on integrating them that i should let them out into the yard to forage as the extra space will help and relieve some pressure/stress as my younger existing girls have retreated to the coop.. Ive had this new girl for 4 days and she puts herswlf up at night with the other 2 in the coop and has laid 3 eggs in nest box in the coop.. Can i let them out into the yard supervised an hour before dark? Will they come back? Should i feed them before i let them out or just leave food in the coop while there out? My main conern is Will they jump my 6 foot fence? I have a main road on 1 side and a big dog on the other? What do i do if they get over the fence?
