cow due to calf

[Anonymous]

Hi I have a dexter cow that is going to have a calf soon, I have done some reading on how to tell when a cow is going to calf, but this doesn't give good information (just very basic info, like she will move away and sit by herself etc). her vulva has become enlarged (how long is it before she calves when here vulva enlarges) and any other infomtion that may help.

Thanks
