I have 3 chickens inside a 3' x 6' coop on top of a 9' x 6' run (the Garden Coop design) and have been leaving their water (on the galvanized steel heater so it doesn't freeze) and food outside in the run, which is covered and snow free. But, ever since it start dipping below freezing and snowing, the ladies have decided that they don't want to go out of their coop! I'm concerned that they won't get enough water or food, so I've been giving them bowls of scratch and using their old chick-sized waterer in the morning. Is it okay to move some food inside the coop? I don't know if mixing their sleeping quarters and eating/drinking quarters is okay.
