When I was quite young we had a "lost" blue bar racer who visited our house almost daily for an entire summer. When he first showed up he landed, clearly exhausted, on our patio and was so thirsty that he jumped up onto my mother's arm and drank some water straight out of her glass, I'll never forget that. We gave him some bird seed too and he went on his way, but every day after that for several months he'd return in the morning for a bit of seed and a drink. We were able to catch him and contact the owner (who lived about 50 miles away in another state) but he didn't seem very interested in getting the bird back. For a while he started bringing a blue check hen with him to our house but she must've been picked off by a hawk. After that happened, my parents made a bit of a fuss with the owner because we didn't want to see "Pidge" get killed coming to our house, and eventually he was picked up and taken back home. That childhood experience kickstarted my interest in pigeons but I was never able to get any until last year. I've actually rescued a number of lost racers in my life but that first pigeon was really what started it for me. He was a very tame and friendly bird and tolerated me catching and handling him as a young child with no fuss at all.
your naming system with your squabs is gonna help though
