I have a few bull runnin with 2 heifers and Ive been having problems with them tring to get out. They have done though by fence twice now and they are always breaking the barn door to get in. In the barn I have a cow with a calf, so im not sure if they are just tring to get into her? I feed them Hay 2 times a day and a very little grain at night. We have a foot of snow or so and they are not grazin at all. They have about 2 acres of pasture they are in now. Am I not feeding them enough? I was told I was giving them too much...They are Angus and I know they are crazy but I didnt think they would push through an eletric fence. any ideas?
