My 1.5 year old nigerian dwarf appeared lethargic and unsteady on his legs today. He was also drooling. I didn't notice him eating with the others, and I hadn't seen him drinking so I gave him electrolyte gel and hand poured him water from a cup. He drank some, but I don't know how much because some poured on the ground. I also administered 1cc of Vitamin B complex via intramuscular injection. Throughout the day I have checked on him and continued giving him water. He is now laying in his hut (it is night time) so I am unsure if he is just tired, or if he's deteriorating. When flashing a light into his eyes he reacted, but only slightly. Any suggestions would be helpful. We are in upstate NY and it is supposed to get down to 32 tonight. He does have his thicker coat, and is under shelter, but thought it should be mentioned.
