So we have a intruder in the chicken coop. There is a crow that is making its nest in the barn of the people who live behind us or somewhere on there property, and i think the crow is watching my chickens cause it knows where they are laying there eggs cause its taking them all. Now my chickens are laying all over the yard because of it, we have 5 acres with pine trees lining two sides and chaparral bushes all over the place so its really hard to find them. I know i need to lock them in but i dont know how to get rid of the crow. Any tips on how to get rid of it. Do you think that putting in a chicken door would stop it or will it just go thru the door?
