I have a 6 week old baby who i noticed a couple of days ago standing with a sawhorse arch, walking with a stiff gate and lower head. I inspected him for any cuts or lacerations which might cause the lameness. Nothing was found.He was still eating, and seemed alert when his mother was near to try and suck. Yesterday morning I found him laying down, with no will to stand at all. When I picked him up, he seemed to cry in pain, and seemed very stiff. When i stood him up, he stayed for a few seconds then went to his knees and laid back down. I felt inside his mouth and it was very cold to the touch. I took his temp and it was only 100.5. I got him under the lights and gave him selenium/vit e gel. Waited until he had normal temp, drenched him with electrolytes several times yesterday. He still can't stand for very long, but is nibbling on the straw and hay in his pen. He doesn't look sick? Open for any suggestions.
