Last night after locking the girls up, I stopped to listen to a series of calls that were echoing through the area. Although what I listened to online this morning doesn't quite match what I heard last night, I can only assume I have at least one GH Owl living around here. I've read so many horror stories about them on BYC. I am horrified! My flock (which includes a wimpy cockeral) free ranges during the day. I visit with them periodically throughout the day, and for most of the 30 minutes prior to dusk. I let them out approximately 30 minutes to an hour after sun up (sometimes later). They get locked up every night. Obviously these owls do a great deal of hunting at night, but should I be concerned during the daylight? Has anyone had an attack during the day?
