I think you have one of those easy make runs (with those coils to keep the runs together - forever slipping!), we have one of them and it has come in essential when we have the foster rabbits temporarily until rehomed, but I split it up so only two rabbits were in it (although even so - its still not everso large at all).
Id never leave a rabbit alone in that kind of run.
Only thing is, you have four rabbits in that space.
I think you might find territoriality may have a large part to play in it!
I have seen our rabbits being territorial about much, much larger spaces - they must be veryso in the wild of course.
It might make life just a bit easier perhaps, if you could find a way of making the run bigger so they don't all get in each others hair so much ? Just a thought.
Although I understand how expensive it can be.
I am planning to lookout for really good quality wire mesh, and just make the next run (fully concealed like our existing mated to our hutch) so we have with the best options for design and cost ....
I could perhaps use in part some of those really useful panels from the run kit although I might prefer something straighter and more permanent/fixed myself and wonder although useful whether those open top easy runs are such a good idea after all!
