I am in the ridges of SW PA. I have 8 7wk old pullets and our weather right now is 50's and 60's for highs and 40's for lows w rain. They have been in our garage without a heat lamp for a week and it gets down to 50 or so down there at night. Do you think the will be ok in our outside coop by now? I plan on bedding it deep w shavings but they are trying to roost now. Thanks for any input!
