So this morning I gave my 9 week old doeling her red cell via syringe (battling anemia/worms right now), then I fed the herd their grain. That included the doeling. I introduced calf manna and probiotics mixed with their grain for the first time. When the doeling got a mouthful of food she jumped back, pee’d, and then hollered. Then I noticed that she had a frothy mouth. She didn’t have it before. It took a few minutes and then she went back to eating like nothing had happened. I inspected her to check for any kind of illness but I couldn’t find anything wrong on the outside. I thought maybe she didn’t like the taste of the new feed. I have never seen a frothy mouth before. And it went away after a few minutes. Has anyone had this happen before? Is it something I should worry about?
