Alright, I wills start by saying, I know NOTHING about cows. Period. However, my neighbors have a huge field full of them. The field is right behind my house....VERY close to my house in fact. They are a bunch of big black ones...very pretty and we adore them. At night they are always gone somewhere and the only time I have ever seen or heard one at night was twice when there was one making a racket by the fence and the next day they had a new baby. Well, they added a bull a day or two ago....I suppose he is a stud service sort of thing (I HOPE he is not here for long). He is now (at 12:47 AM) standing right outside my bedroom window yelling for his women!!! I guess anyway. It is an awful racket. Don't they take a break from mating to sleep or anything! This is unbelievable!!!!
