One year ago I knew virtually nothing about cows but I thought the best way to learn is to own a couple and in the future breed them on a small scale. So I bought an orphan 4 week old angus/charolais female calf from a local rancher and a week later I bought another two day old female orphan hereford/charolais from the local auction barn and bottle fed them both. They are now a year old and appear fat and healthy. Over that period the rancher has continued to advise me as to their care, including my questions about breeding them in the future. A few days ago I learned that the one I bought from the rancher was in fact a twin and that the other twin was a bull. This of course means a 90%+ chance my heifer is sterile (freemartin). Is there any possibility that the rancher and his partner, who have bred and sold thousands of cows for well over 60 years, could not have known that a heifer whose twin is a bull has a high chance of being sterile? In other words, was I duped? I plan to have both tested by a vet this week, but should he also bring his tattoo kit and tattoo the letter S on my forehead for "sucker"? If one or both are sterile, what do I do with them? It'd be morally wrong to sell them at the auction barn without disclosing that so are they worth anything? Thanks
