Tell-tale signs of breeding.
Buck mounts doe and then falls off usually with a grunt.
It is a good idea to check her afterwards just to make sure the buck didn't miss. Sometimes they do. If he succeeds there will be a trace of semen on her vent (looks like a milky liquid).
Generally speaking letting them mount twice is a good idea. I have gotten big litters with just one breeding, two is just insurance.
It is assumed that before you let two rabbits breed that you have checked them of signs of health BEFORE breeding.
- no snot
- no abscesses
- no weepy eye
- no poor teeth
- no vent disease
- animals in good physical condition .. not too fat or too thin.
- no sore hocks
and so forth. You want to breed animals that are healthy, the very picture of health. Anything less is being unfair to the rabbit and not good for your breeding program.
