Also you could use a damp cloth on the broken nail, not icey cold, but cold. That will also stop the bleeding. I would take him to the vet. There is a 24 hour vet here in Bremerton that sees rabbits and they are good. Their number is 360-377-3801. I am not sure if they are open right now, but you can check. Dr Little is very good with rabbits and knowledgeable. So is Dr B, he is just starting out in rabbits but he saw Sweetie and he did really good. Give All Creatures a call and see if they are open, then you can come this way.
Thank you Katie for calling me and letting me know about his broken toenail. I hope that something can be done about it.
