When you get started the poults can be extremely fragile. They are born too dumb to live - almost literally. Their mother is supposed to teach them _everything_ and with her gone they have to struggle to learn it on their own. Because of that, you need to be more careful with them. Raising them with a couple of chicks seems to work best, since they learn what to do by watching the others.
Be careful, turkeys are incredibly addictive. They are much less skittish and genuinely seem to want to be around you. I was keeping one poult inside because he had a cold and the container didn't have a lid. I didn't think anything of it until a couple of days later when this poult had managed to trek the house to find me. I had been out in the yard and when I came in and heard him crying I called out and we played Marco Polo until finding one another. Once I had him in my hands he relaxed and went to sleep.
You want to feed them a high-protein feed because of how quickly they grow. 20-22%, if not more, works best. You can find this in feed stores under different names. If you don't actually have a turkey feed then gamebird and meat/broiler feeds work just as well.
They are very curious. Our hens like to cause trouble in the yard when we let them out of their pen. If we're trying to fix a broken lawn mower they are making funky little trilling noises and chirps while investigating. Then they "help" by taking anything shiny and running off.
The noises are great; to me they're exotic. The trills, chirps and other non-gobbly sounds are unique and would be missed around here if we didn't have them. Even the poults have a softer, quieter cheep than chicks. For some reason a chick's calls go right through me. Ducklings are just as bad. But poults, goslings, quail and chukars are almost soothing.
Don't worry about toms being aggressive. Most are big babies, just like with roosters. There will be bad ones in the bunch, but so far I haven't come across any.
You may want to ask specific questions. There is too much information to tell in a single post without getting specifics
