Hi, I have a 9 month old calve that was eating and behaving normally until last night. This morning we noticed him laying down with his head on the ground, weak and with his belly bigger than usual. He did get up for a bit but soon went back on the ground. I don't know if he might have ate something he shouldn't have or what. Please advice. Thank you in advance for any help you can give. I have uploaded a photo, but unfortunately you can't really tell what I'm talking about.
