I've raised chickens for many years but never had any turkeys. I'm giving thought to getting 5-6 Blue Slate turkeys to raise for the freezer and for breeding purposes. They will be kept separate from my chickens so I'll need some sort of shelter. I understand they need a different feed than my chickens too. I was told this breed likes to fly which may be an issue. I have a fence area available for them that's approx. 75'x85' they can free range in. How long does it take for them to reach butchering age? Thanks for your help!
