Not for the squeamish... Lilac giving birth to a bull calf

I hope you don't mind another video of an animal giving birth.  Lilac actually belongs to some friends of ours but has been staying on our farm.  The kids went out to check on her the other evening and happened to catch her just at the right time.  We're posting this video so our friends' children can watch their calf being born.

I'm putting in several returns since the beginning picture is pretty graphic.  So if you don't want to see it, don't scroll down.  :)
