We have a dwarf Nigerian kid 4 days old now, born #3 of 5, the runt, whose heart beat and respiration are abnormally high. He eats appropriately, although not a lot, got good colostrum early, was definitely weaker and the smallest at birth, and by day 2 his mother rejected him. He s on another dam now who isn t as aggressive about pushing him away (he s #4 for the second dam; those kids are just a day younger than him). No fever. Just seems like heart and respiration problems. Your thoughts?
