Hello all! Wondering, since silkies don't get "regular" feathers, do I need to be more concerned with night time temps when moving 7&8 wk old chicks from brooder to coop? They haven't been utilizing their heat source in the brooder (in the house) for a while now. I'm in NC, and night time lows are in 50s & 60s, day time mid-upper 80s. Thanks!
