We had two more litters a few days ago. I noticed this morning that one of the new kits has a deep gash about a half inch long in his side, about where the ribcage ends. I assume the doe's nails got it somehow. The injury seems to be closed up, but the poor little guy flinched when I just barely touched it so it's obviously still sensitive. He seems strong and otherwise uninjured. Should I treat the injury somehow, or leave it alone? Or should I just say "nice knowing you" and cull? I don't like to see animals suffer, but I don't want to cull unnecessarily either.
