Its been 3 weeks since Penny was treated for Listeria/polio? Anyhow, she still has this head tilt to the left. Tonite, I shut out the lights and all were happy eating their hay. I have the tv muted with the cam because it is raining here and the noise on the tin roof is too much....I was getting ready to turn the tv off and turned up the volume to check them before I did...Penny was really crying out, I was so scared I ran out to the barn barefoot turned on the light and it looked like she ripped the stall apart, there was bedding in her water and she was wet. My hubby is so PO'd at me because he feels that I am looking for bad things to happen with her...anyhow, I calmed her thinking that the bird that had been in the shed scared her...I was leaving so I turned out the light, she started to holler and no amount of me comforting her would quiet her, I turned on the light and saw that she had the left side of her face practically to the floor. Vet says that as long as she's eating and her rumen sounds are good , she's making thiamine on her own, I gave her a thiamine tab anyhow...just for my peace of mind. Her temp is 102.6 so thats good. I just tried to turn the light out again and it really seems that total darkness brings this on....I AM AT A LOSS AS TO WHAT IS WRONG. With the light on, she's as fine as she was before, turn it off and she goes to the floor, her eyes are fine, she focuses, can see me and she can see when I have something in my hand for her. Any idea as to why this is happenning?
