I picked up 2,1yr. old hens yesterday, have them housed very temporarily in a x lg. dog crate at night, and fenced in a 8 ft area during the day, we have build the frame for a 3x4 house with 2 nesting boxes and a 10'by3' run this will be completed today. My husband wants to get 2 more laying hens to put in that house and run and We will be adding 13 chicks to this flock next week, but will have an 8x8 house and a large 20'x20'run. We would like to house the large birds in the small coop and run until the chicks are old enough to integrate the flock, is this adequate housing? My concern is with the small coop and 4 hens!
