So, I have a bred jersey heifer that I'm worried about. I recently purchased her, and she's been an amazing girl. She's super friendly, likes being petted, likes being brushed, and has a great attitude. I've been spending soooo much time with her. Yesterday I started noticing she kept bellowing every single time I would leave the barn. Of course I thought she was scared or lonely and I would go pet her, talk to her, and comfort her. I brushed her for a few hours today, and spent a lot of time with her. I then made dinner, and played with my kids.....the entire time she was bellowing. I went back out and brought a bucket of fresh water and petted her for a little bit.....when I turned to walk out of the stall she kind of stood on her hind legs. I'm not sure what she was doing but it really did make me nervous to be honest. She never touched me or hurt me but I turned around and stuck my hand out. It happens so fast that I'm wondering if anybody knows if she was just happy or excited? Was she trying to mount me?
