I have 3 serama chickens, 1 roo and 2 hens...they are about 3 months old. They have been living in a trough in our enclosed garage since week 1 with two same age silkies. I moved silkies outside to coop BC the other silkie lost her roo to a hawk this week so they are now confined temporarily to the coop. The seramas don't seem as active since the silkie pair left, they just kinda roost all day if they aren't eating/drinking. Should I move them out with others? If not what kind of coop will they need when I do move them, I know they aren't as hardy of a bird and I don't know what's too cold for them. I'm a newbie so as much guidance and info I need is much appreciated!!
