That's what I had to do with my Y/Birds this year Phil and it was no problem, it was the only way I could get them in they wouldn't even land on the loft,landed on the ground every time that they where out flying or racing,the first 3 or 4 time that my y/birds where out on the roof they got hit with a Sparrow Hawk just wouldn't go on the shed or near the traps after that.
