I'm thinking my bull tried to mount a way to young heifer today. She has Blood coming out of her female parts and is walking really slow. She can get around but walks like she has a corn cob up her back side. She was born April 7th so is only 4 1/2 months old. Tried to call the vet, but he's closed. What should I do? Watch her for awhile and see how she does and lute her when I wean in a little over a month, or does this require vet attention?
