I personally don't pet my turkeys, and only pick them up to move them in or out, mine stop running from me when I stop picking them up, then I can get them to follow me. I personally keep mine penned up and then let them out to range daily, I don't need obnoxious turkeys running amok.
Around 7 weeks they should be able to handle 70 degrees full time. You certainly can put them outside on warmer days for shorter times, especially if they are in a warm draft free area. I always wait until June and July to hatch and raise my poults because the temperature isn't such a problem and mine are outside by 2-3 weeks.
Mine like anything red for treats, strawberries, raspberry, watermelon and tomatoes are their favorites. They also like cucumber slices and black oil sunflower seeds.
