Rabbit bleeding?

[Biscuit&Gravy]

So for the past approximately 3 weeks, biscuit will not stop humping gravy (sisters) and got so bad we had to separate them a couple hours a day! Biscuit has chewed half of gravys hair off and now today when I went to feed them and check the heater, there is blood (I think) all over where they sleep! I noticed a few bright orange spots yesterday in the snow but didn't know what it was! And biscuit is orange/red all on her bottom! We got them in June so they aren't even a year old yet! Any help is much appreciated!

Separate them immediately! Do NOT put them back together. If you do not separate them the fighting could get very dangerous and one of them might die. Clean up the blood on Biscuit with a damp warm rag. If she won't stop bleeding take her to the vet, she could bleed to death!!! Check both rabbits over for any bites and if there are very deep bites, you will need to take them to the vet for stitches. For any small bites, stop the bleeding with flour. After it has stopped bleeding, the bites can be treated with Neosporin.

The reason this has happened is that once rabbits hit 4-5 months they reach puberty and their hormones change. The "bond" that they had as babies has broken and they will never get along together unless you get them both spayed and bond them properly.

Separate them immediately. They will continue to attack each other if you don’t. Look into bonding sites ( like @Mariam+Theo put) and take the site seriously as to prevent any more fights.
