We are new to goats and have two 3-week old Nigerian Dwarf bottle babies. We have had them since they were 9 days old. The doe is doing great, eating 5 oz. 3x day, energetic, normal poops. The little boy doesn't seem to be thriving- always been a reluctant eater, we've tried multiple nipples/bottles, daughter has to "force" him to eat minimum amount 8 oz/day now (in 1-2 oz. at a time with her hand wrapped around mouth and bottle.) We've watched many videos and tried a lot of tricks! He now has runny stools, not watery, but soft and has mucus in it. He's wobbly (not stable when he stands at times), doesn't have a lot of energy like his sister, and sleeps/lays down a lot. We are just worried something more might be up. Thoughts? Suggestions? Normal temperature and he is on milk replacer. Thank you!
