My daughter wants peafowl. My husband wants a couple of turkeys. I was considering the turkeys for a few weeks, just letting them strut around the yard until time to butcher them. But a friend told me how destructive they are to gardens, and I have some planter boxes in the yard that I'm planning to fence off from the chickens. So I decided that we'd buy a Thanksgiving turkey from someone else so I could grow my greens. It's easier to find organic turkey than a wide variety of organic greens.
If I got a turkey I'd want a royal palm, but they're so pretty I wouldn't want to butcher them. A broad-breasted wouldn't fly out of the yard, though. They couldn't make it over the fence! When my mom raised them, the largest white tom was 50lbs DRESSED OUT. We had to saw it in half to even fit it in the oven.
My dad tried peafowl once on 3.5 acres of land. The noise wasn't a problem, because they're all country people and that's the least of their issues. But he kept getting calls from confused neighbors wondering why there were peacocks on their roofs.
