I currently have (4) eight week old chicks that appear to be fully feathered and completly bored in thier brooder box inside my dinning room. We have recently been taking them out to thier coop/run in the day times weather permitting but they haven't spend a night in it yet. I took them off the heat lamp in the house weeks ago and they have adjusted just fine. The coop we have for them is un-insulated and not able to support a heat lamp. We live in the pacific northwest, so currently the weather is wet/damp and in the day times around 55 and can drop into the high 30's during the night and will continue to to drop going into winter. The chicks love being outside, our family is completly attached to them and I would hate to loose them cause I jumped the gun and put them out to early. I have experience with my three full grown chickens, but this is my first time raising chicks and need some advise before I make a mistake...Advise greatly welcomed, thank you!!!
