I saw one do it like right now!!! I happened to glance out my window and saw a crow (or raven I was in to much of a hurry to notice) had an egg in his mouth in the chicken run I dashed out the door and ran into the run, he was startled and couldn't find the way out so he dropped the egg. then he found the door I let my hens free range so I just leave the run door open. by now the crows (or ravens) are smart enough to know where these eggs are coming from and if he was in the run I would be surprised if they weren't in the coop stealing right from the nest boxes I have a live trap set with eggs in it but the crows wont go in there. they are frustratingly smart. I can collect eggs often but I'm sure one will get in and get some in between my visits. and I don't want them in my coop anyway I'm not gonna stop free ranging so what can I do to deter them???? is anyone else dealing with this?
