911 three day old kid. Twin birth. No issues. Nursed well for last 3 days. Today he’s getting lethargic. With a stethoscope there aren’t crackles but there is a grunt at the very end of his breath. Gave him Vit B and nutridrench for kids. Also had Vit E first 2 days because of bowed front legs. One thermometer says 104.2 (veterinary one) and the other says 105.8. (Household digital). FAMACHA is 2 maybe 3. Hard to tell as his eyes are so tiny. Thoughts? Sister is fine. He played outside all day but slept a lot. Not hot today and had plenty of shade. He’s not droopy, just is getting more and more tired.
