My 6 month old Dexter bull settled my 8 month old Jersey a few years back, not at all planned, I figured they were both to young, but they had other plans...
She was coming up the breeding age and I had the vet out to check her because I was not noticing her showing any heats.... He checked her and I figured out why she was not showing her heats. She calved out a tiny little heifer with out any help. I stood and watched, gave her a little help getting the shoulders out.
