Have 10 of 'em. They are now in a 6X8' Hoop coop. Had to go to a 3 gallon waterer and they are going through about 2 lbs if mixed chick starter & flock raiser per day. Gettin a lot of feathers. The 5 hens that are in the same run will circle the hoop coop and peck @ 'em if they get too close to the wire. Hopefully they will get to know each other in another month or so.
