One of my does who is (hopefully) pregnant for the first time seems to have lost weight. She's much thinner and doesn't have that "wedge shape." My older doe tosses her around a lot and slams her into walls and everything else imaginable. She also will bite her ears, etc. Is it possible an injury from being batted around is causing her to be thin(ner)? Should i separate the two? Especially since my older doe may harm any possible kids inside of the younger doe? Or could it be worms? She has a normal appetite...should i just pick up her grain a bit? Thanks in advance!
