I have a weaned three month old lamb that I noticed had a little head tilt to him today. Upon closer observation, his head was twitching almost like he had the hiccups but it was a head twitch. He is bright and alert and ate dinner with gusto. One eyelid looks a little droopy on just one side. I caught him, took his temp. ~ 104.5 so I gave Pen G, Dexamethasone, and Vit. B complex. The rest of the lambs in his bunch look fine. Any ideas? In hundreds of lambs over the years, I have never come across anything like this.
