Hi - we just put a new hanging feeder and a hanging water in our run to try to keep the food and water cleaner and not lose as much feed. But the chickens are afraid of them! They wouldn't go in the coop last night - I had to chase them all down in hte yard to get them inside. This morning only one came out of the coop to the run. The rest came out when I opened the run door to the yard. What can I do? Thank you!
