note the responses from people who live in a similar climate may be of most importance to you. I did only feed and water them outside, but this week when winter came with a certain brutality the chooks would NOT come out of the coop. So I have just put water and food in the coop 24hrs. I really didn't want to, especially since I bought a heated water bowl for outside (only $10 on CL) but I can't use it in the coop (too much spilling). But here we are, 2 days of snow and wind and near brutal temps, They have not set 1 foot outside. If the temps stay in the 20-30's they love to go out, but below that...inside all day! looking forward to warmer temps tomorrow so I can get them out and clean out the 2 days worth of poop.
