Odd . . . I just read that link, (

and I didn't get "rabbits are very social" out of it. I saw things like:
With adequate resources, being social does not appear to be a necessity for and may actually be avoided by wild rabbits.
Not surprisingly, subordinate does and bucks had higher levels of cortisol than do more dominant animals, suggesting subordinates experience some degree of chronic stress. High-ranking female rabbits are more active than are low-ranking ones, suggesting that subordinate animals may be inhibited behaviorally by dominants.
Another study found that group housing of breeding does is associated with higher kit mortality and shorter doe lifespan, suggesting that continuous social housing of this group of animals is suboptimal. Similarly, subordinate group-housed bucks in a large, outdoor fenced field had lower body masses, higher adrenocortical activities, and higher heart rates than did dominant animals, mirroring findings in wild bucks. These endocrine and immune responses suggestive of chronic stress in socially housed rabbits conflict with behavioral evidence that animals sometimes choose social interactions.
What I get out of that is, as they say, "it's good to be the king," but if you aren't royalty, life in the kingdom
sucks. The rabbits that scratch and bite their way to the top of the pecking order may thrive, but things for the lower-ranking animals aren't as rosy, even if there isn't a resource shortage (in most cases, a shortage of resources seems to be the cause of the grouping of wild rabbits in the first place). Even though rabbits may seem to choose social interaction, living in close proximity with their own kind
increases their stress level rather than reducing it. If they have a choice between a big, lovely space with other rabbits and a big, lovely space with no rabbits, they seem to prefer the one with no rabbits, but they will tolerate other rabbits if that's what they must do to experience the rest of it.
It's kind of funny - a member posted a few weeks ago (someone here may know who it was; I just remember the post, not the poster's name or the thread it was on) that they have two groups of rabbits, some who roam freely in the house and others that roam freely in the yard. One of the yard group had a medical issue that required her to be isolated for a while. When her treatment was over, the rabbit was returned to the yard, but she wanted back in the house and back in the cage, apparently preferring the relatively confined space with no rabbits to sharing a much larger space with several rabbits.
If a person wants to keep pet rabbits together, that is entirely their business, but if breeding is the goal, it sure looks like for any but the most dominant does, both the mother and the babies are better off when housed separately.
