We've had so much fun with all our birds that I wish we had started much earlier--and wish we'd added turkeys to the flock sooner as well. I say "go for it!"
We thoroughly enjoy our little band of turkeys and have never had any trouble keeping them with the chickens (and ducks). Our original pair, a BBW hen and a BBB tom, avoided the dinner table because A. she was entirely too sweet to butcher (and we thought turkey eggs would be grand), and B. my husband was in the hospital when Mister was supposed to have his date with destiny. Mister had a stay of execution and returned the favor by becoming a good guardian. Strangers coming onto our property think twice when they see him because he's an impressive bird--a big boy with very big feet. One of our local sheriffs remarked that he had never seen such a large turkey and if we ever had any problems, we should just let Mr. T out. haha! He does fancy himself to be "all that," but he was hand raised and has never been aggressive toward us. Too many cuddles and kisses, I guess. Had he been problematic, he would have gone into the freezer no matter how old he was. I have seen him get after our rooster, but he's such a lumbering oaf Bruce doesn't have any trouble avoiding him. If for some reason any of our chickens has not made it into the hen house before dark, Mister Turkey remains outside until we locate the wanderers. On the rare occasion we can't find a chicken, Mr. T puts up a considerable fuss about being locked up. He will stubbornly remain outside, even in a rainstorm, until we've recovered the missing girls.
When last spring rolled around and he was a year old, we were given to believe Mister T wouldn't taste very good so we just let him be. He cruises our yard, always nearby if I'm outside, gobbling, thrumming and fluffing himself up like a Thanksgiving poster child. Poster turkey? He follows he around the yard while I work, walking at a stately pace, rarely in a hurry. I believe his presence in the flock was a good deterrent for predators until recently as he seems completely unperturbed by the possum that keeps entering the hen house (and is in danger of losing his life if he doesn't cease and desist). He was single-minded in his interest toward Mrs.T last summer and I do worry about her because of his size. I've read that big BB toms can do serious harm to hens and we don't want that to happen. She's more reserved than he is, but she is a sweet bird, gave us a considerable number of eggs in the summer and fall, and we had eggs inexplicably hatch. I now have a pair of five month old BBW toms that are two of the most delightful creatures we've ever had on our little farm. From the get go they were silly and spirited and affectionate. We raised them inside with a pair of duckling siblings (fearful that Mrs. T, for all she was sweet, would crush them) and they are the funniest little (well, not so little now) fellas. They cavort like puppies, singing and hooting merrily everywhere they go. All I have to do is call "hey, boys!" and they come running. In the morning, they circle the food bin until it is opened for breakfast. When we set the eggs we had determined were actually fertile, I had visions of a freezer full of unlikely crossbreed turkey. What I got were what we call our Impossible Poults and we're so attached to them (and them to us) that I'm having a terrible time thinking about eating them. We kept waiting for them to display some Bronze characteristics, but they are exactly like Mrs. T and she is obviously very proud of them. We now realize we're probably courting disaster with three toms (and they eat an awful lot), but so far the boys are too young and goofy to cause any trouble. Like the other poster, we often find them--and most of our lovely chicken girls--at the back door (they'll come right on in if you aren't careful). In fact, they marched through a considerable snowfall yesterday to ask for treats and check the snow under the wild bird feeders.
After hatching out the first turkeys (we had three, but lost one) we attempted to set additional turkey eggs in the fall (Mrs. T began layng very late in the year) and while some of them began to develop, we eventually lost all the eggs. Not sure if that was a genetic issue or incubator issue because we did have some trouble with regulating temps. We'll certainly try again this year as I'd still like to put some turkey in my freezer. In the meantime, these guys have become pets. They aren't as "pretty" as Mr. T with his iridescent feathers and classic Thanksgiving Turkey appearance, but they seem to have great senses of humor and we really enjoy them.
