Those are selectively bread to do 1 thing, overeat, pack on weight, and become food. If you don't butcher them they'll all just up and die on thier own. Now egg hens can last 3-5 years easy, but those don't eat themselves into oblivion like meat birds can. My suggestion, butcher and part them out (breasts, thight wings etc) and use the meat in something like tacos (a roast chicken in the middle of summer may make her wonder).
Raising meaties can be good for a kid, but she's attached so don't mention that henny penny makes good tacos, ever. Untill then make a huge fuss over the new birds, and she'll be ok.
