I know the rule of thumb is generally 2-3' per bird in the coop and 8-10' per bird in the run. My coop is 4x8', the upstairs is about 4x3'. I have kept 4 large breed hens at a time in this coop for several years without any problems. I let them out daily in the evenings to roam my entire backyard for the last couple hours of daylight. If I am home on the weekends, they get free roam of the yard about half the day both Saturday and Sunday. My BO recently died of unknown causes. I don't want to buy just one chick and reintroduce to the other 3 girls, but I am concerned about buying 2 chicks and eventually keeping 5 large hens in this setup. Do yall think it is enough room for 5 if they are let out daily? I sometimes leave town on the weekends, so they would be contained in this for up to 3 days at a time with no breaks. Thanks.
