Well last wendsday she actually walked with a slight limp NORMAL. It was awsome!! Then on thursday night I noticed something on her knee so I got her behind a gate. I examined her knee and found two holes in her knee. One on top and one under and draining puss. So off to the collage friday morning for a x-ray. Found no forien object and the infection is not in the joint so that was good news. Left the pair there for the weekend so they could open up the knee and drain it well and put the heifer on IV antibiotics. As of saturday she was sore on the leg and not using it much but doing fine. Will see in the morning if they get to come home. Now before you guys all say didnt you see the holes earlier remember I check this calf daily since she was 3 days old and two vets examined her at 7 days. None of us saw anything that would have lead us to believe she stuck it earlier. No dried blood, or messed up hair or the mom licking that spot more than others. I am still kicking myself that I did miss something. Well let you know more tomorrow when I do.
