Sounds like a potential new reality show "The Chicken Nanny" . . .
I have done this with some local families that can't have (or don't want) chickens outside, but have kids with a lot of energy for playing with chicks. It's educational and teach responsibility, and it's a pet that is designed to be temporary, no issues with mom or dad having to care for the pet after the kids have lost interest (not implying you'd lose interest, but kids sometimes do).
Of course sometimes the kids fall in love with "Belle" (the actual name of one that came back to us because "she" started crowing) and want to keep them forever.
Gave nephew eggs and incubator for his kids to watch them hatch.
A friend of theirs wanted to raise the chicks so the kids could watch them grow.
A friend of that person wants to start raising chickens!
I may sell chicks without ever seeing them!
I did, however, offer to take them at any time and to take the roosters off their hands if they don't want them. As long as they don't ask where they are going.
