Yes, you MUST raise them for food. They make terrible pets. Ignore all that chirping, gobbling, squeaking, and cooing. Pay no attention to their innate sense of curiosity. No matter how flashy Tom looks when he's strutting in the sun you must always keep in mind "I AM going to eat you!"
I tell all of my customers that. Especially the ones who tell me they are definitely buying them to raise for the holidays.
Some of them even manage to actually do it.
The rest have mobile yard art when they discover that turkeys have personality.
The important things to remember is that turkeys are not chickens! Don't try to feed them like chickens. If they are still poults then they are going to need a higher protein feed than ordinary chick starter. What you want is gamebird starter. If it's not labeled as such it may be labeled for quail, pheasants or one of the other game breeds. Optimal protein is in the 28-30% range. Failing all of that and if you have a
Tractor Supply in your area they carry a 24% protein chick starter. The birds will grow a little slower, but still manage to reach their potential. If you just can't find anything higher/better than ordinary chick starter then supplement their feed with something like chopped hard boiled eggs and some dark green leafy vegetables. Chop them up together finely at first then more coarsely as they begin to grow. No more than what they can eat in about ten minutes or so.
If they are day olds when you get them you'll want to be make sure they know how to eat and drink. Dip each of their beaks in their water then set them down on top of their feed. Normally I use the bottom half of an egg carton which allows them to get into it, but hard for them to scratch the feed out. Usually only have to do this once, but occasionally they'll be a little slow on the uptake so you may have to repeat it every couple of hours if you're not seeing them eat or drink.
Make sure they are kept properly warm because very young poults chill easily.
Depending on your local weather you can take them out of their brooder at around six weeks if it is sunny, warm, and dry. A little longer if it's cool or wet and especially if it's cool and wet.
Other than that you can treat them pretty much like chickens. I've found them to get along with smaller birds OK. Once in a while an obnoxious rooster will get crossways with the turkeys. It will be the hens that take him out, not the toms, if it happens so watch out for that, but I've never seen it happen a lot.
Good luck!
