Not sure if this is the right place or under "Broody Hens," but I'll try here. Our first ever broody hen has hatched out 16 chicks that are now 3 weeks old. They have been occupying a spare stall in our barn here in central Virginia, where night time temps are dropping regularly into mid-40s. We have a moveable coop (3' x 4') attached to a somewhat mobile run (6' x 8') inside our main ranging area, which is two lengths of electronet fencing. We were thinking of moving the momma hen and chicks to these accommodations soon, but we're wondering if it's too soon? We've only offered supplemental heating the first week and only at night, so the chicks have been getting used to a wide-range of day time temps that have fluctuated from high 30's twice in the AM to mostly high 60's. Their wing feathers are growing nicely, but obviously they have a long way to go. Mama manages to get all of them under her somehow when she's settling down. Also, at what point would you let the Momma and her chicks mix with the rest of the flock? Our flock is a mix of 7 mature hens, 6 pullets, 1 mature rooster and 2 others that are close to mature (all co-existing more or less peacefully as this is a lot of room for ranging), but we also have 2 Muscovy drakes (about 15-18 lbs each) and 5 Muscovy hens. The Muscovies are fairly new to us since we've raised them from chicks when we bought them about 4 months ago. They get along fine with the other birds and vice versa. We have a pop hole that would allow only chickens in/out of the coop when we decide to mix the babies with the others, but I am wondering if this is enough. Would appreciate any thoughts or suggestions!
