Doen't know where the "kicked up" rule came from; or even if there is such a rule ! As far as I'm concerned, the only rule about what rabbits count, is it MUST be the rabbit you slip on that counts; in other words, if you slip on a rabbit, (a runner, squatter or kick up) and the dog misses, but catches another rabbit from the same slip, then that rabbit does't count ! LDR's at work, but he'll probably clarify when he gets home, as this is only my opinion, I didn't make the rules.
Cheers.
P.S. If rabbit is being ran and it is kicked by the slipper during the run, these don't count towa
