When do you move your chicks outside? I know they aren't ready yet, but was wondering when. I have (2) 5/6 week old silkies & (3) 3 week old mutts & (5) 1.5 week old mutts. The silkies are getting their feathers in their heads now, & the 3 week old mutts are almost completely feathered up to their necks. They will be going into a predator proof 5x6x10 dog pen off to the side of my run (I normally use it to separate a hen and rooster if I want specific babies).
