Recently I've seen a crow near my chicken coop. I have found crow feathers in the run. Today a crow was on the other side of the run fighting with my silkie hen through the fence. Then it decided to fly inside the run and walk around. At that point it heard me knocking on the window and flew away. I have chicks. 3 weeks olds and 6 week olds. They currently live inside the coop 24/7, but I plan on moving the bigger ones out at 8 weeks old. They're silkies. Could that crow decide my 8 week olds look like a snack? Could I do something to scare the crow away? I know they're very smart birds and can't really be tricked that easily. I could try putting a net over the run. At what age would they leave my chicks alone? I really love crows, but I won't tolerate them messing with my chickens.
