Dogs. My first five chickens were roosters like the one in my profile pic, but I loved them. One Halloween, though, we came home only to find two wild dogs in the yard next to two dead roosters WITHOUT WINGS. The wings were in the dogs' mouths, and they were getting ready to take off with the...
Your daughter shoud be fine. Bobcats and other smaller animals(coyotes, foxes, raccoons, etc.) are generally afraid of humans and avoid human contact. They will, however, jump at the chance to get any small pets, as you can see.

When the chicks are still young(a few hours old) and their wing feathers are just plasticky sticks, you can tell by the length. If the secondary feathers(closest to body) are even, it is a rooster. If they are uneven, it is a hen.
