There is a lot of info you can read about general turkey care. They main thing I can add to that is that you may not be able to kill them when the time comes. They are much more people friendly than our chickens. I was moving our Midget White trio to their winter home yesterday and walked by 2 guys on the farm that were making comments about eating them. I told them that if I put the hen down, she would follow me to the chopping block of her own free will, so they would never be eaten!
I do hope to hatch poults next spring, and I'm sure some of the ones I sell will end up being eaten, but we can't raise turkeys for food here. Ours all all heritage breeds, besides the aforementioned Midget whites, we will (hopefully) have Royal Palms and Mottled Blacks. In taste tests, the MW's have consistently beaten out every other breed, and they supposedly lay better than most as well. They did lay a lot of eggs well into the fall, long after our other hens had stopped.
