With our cattle, we only want the best for them! We choose to leave them on the Dam unless absolutely necessary for their safety and/or health. While I do frequently purchase bottle babies, we will not pull calves off moms intentionally to create them. This isn't good for the Dam or the calf. Calves will mature slower and stay smaller in the first year or 2 when on the bottle and that is a marketing strategy of a lot of bottle baby sellers. We will give our best guess at mature height at the age of 3 and older but it is only a guess that we can give. Any breeder that promises a calf to be under an exact measurement at a certain age is being untruthful. In my 30 years of raising cattle plus my families 60 plus years of experience raising cattle as well, we know it isn't something that can ever be promised. So if you do not purchase from us, and find your perfect match elsewhere! We emplore you to do your research and whether you are a customer or not, we would be happy to answer any guestions!
