Thanks, I can feel the calves on the other 2, (1-cow due mid to end Jan, 1-heifer due beg-mid March) The others are getting big, but she has not changed in size.Did not know it came be common for them t loose a preg early on. our cow has held all 3 years. The other heifer has held. How common is it to reaccure for them to loose another preg? I really do not want to keep her around if she is not going to give us a calf every year. we are trying to raise club calves for our son and local kids.
