Hi, I am new here and a new chicken owner as well, first post. This is a great forum and I have learned a lot. Raising chickens along with twin boy 7 year old boys and a 4 year old daughter is a blast too, The boys actually asked for the chickens for their Birthday!! I have 3 Orpingtons, 3 Wyndottes, and 2 Aricanas that are 7 weeks old. They spent the first 4 weeks in the guest bathroom (in a box) under heat and are now in a 22' x 15' run with a house. The temperatures here are getting down to the 20's and 30's at night so I have kept the light on at night to keep them warm. They had been doing well walking up the ramp at dusk to enter their house but now they are all roosting quail style outside on the ground. My questiuon is, is the light keeping them from getting the rest they need and thus they choose to sleep outside or is their something else? I go out each night and scoop them up and put them in the house. Any help is appreciated and thank for all the advice I have recieved by just reading other posts. This chicken stuff is addicting!
