This morning, when I let my little 5-6 month old buckling out for the day, he acted very strange. He vomited a bit or at least I classify it as vomiting. He spit out a gob of chewed on hay/cud and refused to eat for a good while... He's eating now but being very finicky. He's usually into *everything* food wise and well, Mr. Hyper in general. He did get into a big no-no plant last night... He ran to the front yard and I followed him, however, I'm not as fast as him and he grabbed himself a mouthful of azalea and gobbled it down before I could get there. He's also been picking up dead mimosa tree blooms off the ground and eating red bud tree leaves but by what I gather, they're not toxic... they're just new to his diet, I suppose. Oh, and he's also got hay that is new to him... The rest of my herd is fine with it but I'm wondering if he's not... It's high quality Coastal Bermuda. I give him a handful of alfalfa but it's not his basic diet due to the fact that my vet doesn't recommend it for bucks because of urinary stones. When I checked on him just now, he's lying down in the shade and while I know rumen noises are normal, his tummy seems unusually rumbly and he's very burpy. He will eat his favorite foods when offered, just not with the usual eunthusiasm. Both of my vets that treat farm animals are at the cattle sale and won't be in til' 6:30 pm so that's why I'm asking here in case I can do something in advance or see if I need to drive my boy 2 hours to the other vet. I feel like if he's eating, he's okay... but then, he is my spoiled boy so I don't want to just let something go.
