We have found it very hard indeed to find a suitable home for a trio that we have had for rehoming for a very long time. They are a young family of mum and two sons, nothing wrong with them, except they are French crosses so size dictates much larger accommodation - but then for anything than a pair it would need to be big anyway.
Ours have had only one enquiry since they were listed on Rabbitrehome.org.uk last year but that turned out not to be a genuine offer.
You may find someone if you are happy to bunny run. But homechecking for a group at distance may be more difficult that locally where you can actually go and see for yourself.
