Turkeys are funny, it often depends on breed and breeding whether they're smart or not. My BRs are horridly smart and busy critters and I love that.
Yeah, they're messy - chick poop x 5. I don't mind, they're much more companionable. Laura calls mine Turpeys. Turkey Puppies.
They call for me, when I let them out of their pen they run to me, many leap in my lap, they all have to say HI and they follow me around the yard on chores, eating bugs and greens, looking at what I"m doing. If I sit on the deck stairs they all come to sit in the sun, stretch, sit on my lap to be petted or settle in on the dog bed. Twelve BR babies in the space of a few feet.
A turkey will look you in the eye and consider your face in a way no chicken ever will. They're good babies, and the eldest pair are still sweet Momma's birds at over a year.
Nah I wouldn't skip the mess for the companionship. They're amazing. I love my chickens but until you've met a bright, thoughtful turkey who loves you, you just don't know what it's like.
I just sold a bunch of flighty, brain dead Calico turkeys. Hated em. Not all turkeys are equal. I'll stick with my BRs and look maybe for another breed with actual brains. The Calicos were not good at all. Raised exactly the same - they were distant, flighty, mindless.
I keep the animals that tame themselves, that come when called, that think their way out of trouble. I don't have time or energy for the ones that cannot or will not.
