Here's a massive update. I will answer any questions asked here instead of replying separately.
So I went last night. She has I think 3 pairs of rabbits (some have 1 neutered, I think one is a boy boy) and she seemed very confident that these have been together for a long time and no babies have happened. I couldn't argue with her on this (she was very defensive and also was incredibly difficult to get any information out of at all.. incredibly frustrating). There were 2 adult boys separate. I left her with all these.
I felt I had absolutely no choice but to take the two litters and mums. There was no way she had the space to separate or money or care to neuter or spay. This had to stop and this was the only way.
The 5 youngest ones and mum are very quiet but I have seen all babies and mum drink water and nibble at food so I'm not too worried. The older ones couldn't possibly be happier. They are all binkying and going crazy but not skittish. Just incredibly happy to have so much space! The mum is very hormonal and has been have spurts of time of humping and chasing the babies. Over night when I can't keep an eye on them I put the mum in a XL dog crate which was perfect as babies can crawl under and easily get in to her when they want and also get away when they want when she is being too much. I think this is also helping them become more independent for when I will be separating them soon. The older babies are showing no current hormonal behaviour.
One vet has offered to sex the older litter of 6 rabbits for £26. I have very kindly been offered a donation of £40 from someone on another group. This will go a good way to getting all 11 sexed and separated.
Regarding P@H, I feel like it's too far gone for them to help in any way.
I have a few people who are already interested in rehoming. They seem rabbit savvy and the fact that they specifically want to rescue rather than buy gives me hope! Please could you advice me on the right questions to ask and things to say to make sure they are suitable? I can think of lots of things but don't want to miss anything and would love tips on how to do this properly.
I have more than enough space and donated cages at the moment for them but will likely continue to need more cages/hutches/runs as I begin to separate. I've tried to attach a picture of their current set up but I will make it even better today for them and move the bed out the corner so they have more space.
Any other advice or tips would be helpful. I know you all just want the best for me and the rabbits and I appreciate all your concerns. I am so so determined to make this work.
