Just a question, what is the longest you have ever had a cow hide a calf out? We have a hereford cow that has kept her calf hidden for over a month. She has a large bag,and she has been sucked but we cant find the calf. We have taken the four-wheeler out and looked for her but we still have some places that we cant get to, the tornado left alot of damage that is taking forever to clean up. So, has anyone ever had a cow keep a calf hidden this long? Her calf was born healthy last year but got stepped on and died, wondering if maybe she is a little gun shy about bringing her around. Any opinions?
