HennyJenny, I totally understand. We purchased two BBB last year. Thanksgiving and Christmas were their names. Ended up being a tom and a hen. They were like big dogs! They'd come lay with me on the grass, come running for treats, Mr. Turk (thanksgiving) would gobble when you whistled at him. But the time came, last november, when the deed had to be done. And he had gotten so huge that life was hard for him.
The turks free ranged with my chickens, walking up and down our driveway (about the length of a city block with a small incline). Mrs. T (christmas) started beating the crap out of him! She knew he wasn't gonna last long. We set a date, and low and behold the weather turned nasty. With good intentions I made up a bed for him in the horse trailer. Nice and comfy and out of the weather. How would we get him up the driveway? He wasn't walking much. So I decided let's put him the kids wagon and pull him up the driveway. He did not like that! Freaked out and had a heart attack! So I had to dress out a 60 pound turkey in the freezing cold, dark no less, while hubby went off to night shift. But I was spared having to put the knife to my "buddy". Boy did he taste good. We were atattched to him, he WAS a big pet, but we all knew what his purpose was. I thought my three boys would have a hard time with it, but they took it in stride. We had talked the whole summer about what the turkey's purpose was, how we were giving them a much better life than the factory farmed birds.
Mrs. T started laying some huge, excellent omelet eggs, so she got a bit of a reprive. But she won't make it another harsh winter. So to the stew pot she goes. It will be hard, but it's her best interest, and it was her purpose. I'll miss feeding her apples and tomatoes and strawberries tho....
Having a "pet" get old and in frail health is no easier tho. I just had to have my 27 year old mare put down. Hardest animal decision I have EVER had to make. It's hard either way.
I purchased some Royal Palm poults this spring, only have one left. He's a bit of a pet, but we'll see.
