I heard this said before on BYC, but didn't believe it till today. I heard the screeching of a hawk!!! I thought, "Am I going crazy, or do I hear a hawk?" Sure enough, there, through the trees I saw two red-tailed hawks circling high over head. I don't live on a farm and have NEVER seen a hawk in my neighborhood before, although they are on Long Island. I do see them every time I drive a little farther north toward the farming area, but where I live it's wooded and near the ocean. Only thing I've ever seen flying over head was a seagull, crow, raven, and quite often aggressive blue jays(my chickens chase them away). So, I'm a little stressed now! I let the chickens free range for 2 hours in the morning and the rest of the time they are in the run which is covered with bird netting. Do hawks come after full grown chickens? Will they grab them out of my wooded backyard???
