Well I'm trying to get back into having cows after venturing off. I purchased 8 12 month old heifers and have them in a pen at the barn getting them used to me and calmer. They are out of the same stock I had when I sold out. Mostly black, one baldy and a charlais. Should I wait until they are around 15 months or so to breed? It feels good having cows again! I want to purchase a couple of cow calf pairs....that might help calm them more?
