Hello! A family of crows have come to our house. In the morning it is very loud. Today I spied and found that a group of about 7 were flying in and out of the chicken run and eating chicken food. I think some of them are juvenile birds because of the sounds they are making. We let our chickens free range and leave the doors to the run open. I don't think it is a good idea for the wild birds to be in the run. This has never been a problem before. We have had chickens for 3 years. Any tips on what I can do to deter the crows besides keeping the run (and chickens) closed up?
