We picked up our first chickens, 4 started pullets on Saturday, 72 hours ago. The coop was not finished the first night and they huddled under it. The next night 2 huddled under, one in and one at the open pop door. Last night two inside and two on the pop door. They don't seem to be eating their layer pellets, the kind with extra Omega 3. They drink and peck at a handful of scratch and will eat the occaisional worms or grasshopper in their covered run. Do I need to closed the pop door for them all to roost inside? What do I look for to tell me they aren't adjusting to their new home?
