HI there. Sorry, this sounds terrible. I am sending ultra big vibes
I have had a similar problem though on an incredibly smaller scale.
I thought I had a bizarre coincidence of dental bunnies in my group who suddenly developed dental problems and even more bizarrely needed dentals in days of each other. It didn't take long to have suspicions about this. No diet changes or ANYTHING made a difference. I had approximately 2of my 5 buns a week in stasis at one point.
My thinking has now shifted completely to an EC connection, so has my vets. When one of them developed full blown neurological signs, they all got treated with Panacur and anti-inflamms and ALL improved - from bloat every 2 days to none for months. Until that is, Marcy's head has started tilting again and they all independently got bloat over a 2 week period (my hols from work too). That's far too much of a coincidence for my liking
Little is known abut EC's affect on the gut in bunnies - it can granulomas like Crohns disease in humans but very quickly (thanks to SarahP and Elve's research) A lot of vets seem unwilling to make this link. Mines pick up quite quickly whilst on Panacur, SarahP's do too.
I'm not saying that this is the problem, by no means, but the hairs on the back of my neck stand up when I hear about multiple bloat /stasis bunnies as I remember the hard work and I wish I had considered EC earlier
More vibes
