These four rabbits (3 females and 1 male) need to be fixed before I bond the male and bring them to the rabbit cottage.
I can find a spay and neuter clinic, and I'll raise the money, I'm just not sure how to care for them afterwards. They are not in my possession, so the voulenteers would be caring for them there.
I'll do lots of research first of course, I just wanted to ask y'all first so I know where to start.

Keep them separate post spay/neuter for 4-8 weeks, so the hormones can die down, then decide what bonding process to try. There are no hard fast rules to bonding. What will work best depends on the personalities of the rabbits involved. Doing a group bond may work best, or doing pairs and then bonding the group. Or you may find that some won't bond into the group, will bond as pairs but not as a group, or won't get along with the other rabbits at all. No way to know until it's tried.
