Hello! I am new at this venture and would like to know if anyone uses their heat lamp during the winter. I am using it now as my new flock is 5wks old, but didn't know if I needed to use it much come December, when they should be fully feathered. Can anyone help me?? I also bought some Pine shavings the other day to put down in the coop, along with the straw I have down already. We are in NW Oregon and the nights have been low 40's last couple nights. The girls seem to be doing fine with me having the heat lamp on a timer to come on and go off in intervals.
