I am hoping to get some good advise on exercising my newly rescued pigeon (two weeks with me now). She appears to be a white homing pigeon. I have her set up with the right housing and amenities. I understand that regular exercise is important. My concern is that once I release her into the house for the first time to roam freely, she will not return to the cage. How can I lure her back in when I need to? I've heard and seen videos about professional trainers using cans of nails that they shake to get them back in and they are rewarded with feed. Thanks in advance for your tips.
