I've got three full grown hens and two that are around 15 weeks that free range in my urban backyard. I caught a redtailed hawk this morning trying to snatch one of the little ones! I saw something big swoop by the window then heard the birds freak out. I went out and found the hawk sitting on the fence. My going out scared the hawk away. Everyone is okay. I went ahead and locked them in the run until I can settle down a little. My question is, is the hawk unlikely to return after an unsuccessful attempt and then me scaring it off?
