I'd like to keep my pellet feeder in the coop due to rain and vermin. But my new hens won't eat unless I throw pellets in their run or move the feeder outside. They basically just sleep in the run. They don't even bother to eat the scratch I throw on the coop floor at dusk but just go straight to their roost. I open their door pretty early in the morning, they are still on the roost but head straight outside without using the feeder. How can I get them to come in to eat?
