Alas, there are no young ones in my neighborhood to see to feeding my three girls when I will be gone on an upcoming trip. So I purchased a feeder with a lid and a step: when the chicken steps on the step, the lid opens up and they can feed. When they get off the step, the lid gently comes down. [small birds can get through the coop wire and like to eat the feed] Although today is only their first day, they don’t seem to cotton to the new system [what else is new!] Any suggestions? Would appreciate help. Many thanks.
