After dealing with one season of supplying chicks to friends, I have come to the conclusion that once a bird leaves my property, it will not be coming back. I made a promise to one gentleman that if he ended up with roosters, I'd take them off his hands. He in fact ended up with 2 roosters, and I told him what day I was butchering, and he could bring them that day. A week later, he again asked me to take them back. I had told him that due to biosecurity, I would not take them back unless they were going immediately into my freezer. Not wanting to butcher again, I found a family who could use the meat. They drove to the friend's house, picked up his 2 roos, came to my house, picked up a problem hen... problem solved. I had an other friend call me in a panic asking me to take one of my birds back who turned out to be a roo, as well as several other roos she ended up with. No thanks. The one bird that did return to my flock, came back as a 3 week old chick, and it has worked out well for me and him, as he's a very nice roo, and has good blood lines for my future plans... and I knew the flock situation he was coming from... he actually was still in an inside brooder. In the future, once a bird leaves, it's not coming back.
