I, unfortunatly, also had to go through this with my buns at one point as well. 🙁
My three girls were all very loving towards one another in their early months, so I’d always thought that they’d have no problem. At around the age of 6 months, though, one started getting more dominant over the others. This behavior progressed, until the point of her pulling fur from the others, and gathering hay. When she started doing this, soon the others started doing the same behavior. I was very alarmed, as I had no idea why they all were pulling fur from themself/others, and was quite worried. They’d continued to do this, so I had to separate them.
After they were separated, they all still continued pulling fur from themselves, as well as gathering hay and other materials for nesting. What I did – to make it so they didn’t keep pulling fur – was I gave them extra amounts of hay for bedding, as well as cotton for soft padding. This helped greatly, for anything I gave them, they took. It’s hard seeing our bunny girls in so much stress. 🙁
Are there any vets in your area that could spay them? After I got all of my ladies spayed and started the bonding process, their relationship – and overall interaction – became much more positive. 🙂 They’ve also warmed up to me much more as well. 🥰
Wishing you the best!!
