Kareen, is it worth asking the local RSPCA branch for some neutering vouchers so that they can all be done. I would hope that for large nos of bunnies, such as this, that they might help. You are taking them in, which saves their resources and space, but I would ask for some vouchers. Its worth a go.
Neutering vouchers? never heard of them! but will look into it thanks.
This case was a while ago now (feb) I informed the SSPCA and they took over. I hope it is all under control now
