I have 9 White Homing Pigeons. The oldest is 4 months old, the youngest 7 weeks old. I have been letting the birds fly and explore from my loft. They do great! When the leave they leave hungry. They fly for approximately 1 1/2 - 2 hours then return. Here's where the problem lies. (A month ago the birds I had were attacked in front of my loft by a hawk.) When my birds return now they land on my neighbor's roof and stay there until almost dark then they'll return to my landing board and trap quickly. I've tried rattling & whistling as I've done each time I've fed them. But there's no reaction from the roof. For a week I kept the birds in the loft. They came to the feed as soon as I start rattling & whistling in the loft. Today I let them out for the first time in a week. They did the same thing, flew, returned, stayed on the neighbor's roof and trapped at dark. Since they didn't return today when I rattled they did not get fed. I feel like it's a habit for them. So I was thinking about keeping them in 2 weeks. I'm a new flyer, any suggestions would be greatly appreciated.
