Hey people. This lamb was found as a newborn one morning severely hypothermic and barely alive. We managed to revive it and we've been bottle feeding it for the last 3 months. From the beginning it had a hard time walking but it's always been especially week in the hindquarters since then. Recently I've been noticing that it doesn't take much more than a bump to knock him flat, although he manages to get around quite well otherwise. Any thoughts on what could be causing this weakness? He's small...around 30 lbs. I wormed him with Ivermecton recently and he's had hay, minerals, and concentrated pellets all his life like the other lambs. Thanks!
