We began having chickens last year and decided to try raising a few chicks because we so enjoyed our adults. We decided to add 6 Silkies (2 Buff, 2 White, 2 Blue) that are 7 weeks old today and 6 Tractor Supply Red Pullets that are 5 weeks old to the mix. Last week we realized that at least one of our Silkie Buff's is a Roo. He has the red comb and waddle. Just to add more fun to the mix he started his first attempt at crowing this morning. After getting over the awe and shock of his squeaky wheel sounds I am realizing that keeping them indoors may not be an option much longer. We live in the southern part of Oklahoma and the temps outside range from low 50's to low 80's any given day and in the 40's at night. The chicks have all been outside on the warmer days but I want to make sure they would be ok if I permanently placed them outside. My question is what do I look for when I read that they should be fully feathered before they can be placed outside?
