JUST WOW! I mean, I have acres, and bigger facilities than most, but I don't have facilities for 80, even temporarily, and not in addition to my existing flock. My "grow out" pen is about 44 sq ft, I suppose that would do for the first week or three?
GOOD LUCK re-homing!
Honestly, as I look at my culling project and what genes to bring in in the future, I keep looking at Welsummers. A lot to like. Good luck on your coop build, may it go quickly and smoothly.
/edit and I should be able to swing by at least one, likely two, TSCs today (in different districts)...
