My little girl goes to a fab nursery and they have a lot of animals including: hamsters, giant snails, fish, chickens, guinea pigs and 2 buns (which came from my accidental litter)
In all honesty, I didn't mind them having the buns at all. I gave them all the info they needed and all the other animals are kept amazingly well.
They have a beautiful hutch outside and nursery are currently building a run. I am responsible for neutering, vaccinations and any vet visits (I pointed all this out when they took the buns on)
I am also responsible for them over long holidays.
The nursery staff are paid to go in over the weekends (at least twice a day) but the guineas go home with the manager. The nursery is also next door to a farm so the owner looks in too.
The children are not allowed to hold the animals, instead, they sit in a circle on the floor outside and then staff hold the animals whilst the children are allowed to stroke them.
I think they do a fab job but then, this is a nursery who goes above and beyond, who have 2 large gardens and an incredible building...

I think that aren't for every nursery though, especially a house rabbit!!!! After discussing buns needs with nursery, they weren't going to get a bun at all. It's only because I am there to check over them, take them to the vets etc that they have Domino and Parsnip now.
