Welcome
@LadyGuinevere 
if you cut up foods like cantaloupe and watermelon, you can give them to your birds. 7 RIRs will get big, what are the dimensions of your coop and your run? Do you plan out letting them free range at all? Aww, they're cute I remember that age well! We actually had a discussion a few pages back on heating/insulating the coop and a lot of good discussion there. I have 6 barnyard mix hens and one mini rooster. You don't need a rooster and they aren't for everyone, but he really has brought a lot of good to my tiny flock.
Feel free to ask any questions! I had a ton when I first started out, and even now I still have some. This group has been very helpful!
