Sorry about one-handed video quality. this is my 6.5 wk old runner. She was fine last night, but limping this morning. I can't see the problem...perhaps someone can help me pinpoint it? Maybe a little swollen? Or tell me what else I need to check? She was separated from the big ducks last night...roomed with the smaller mallard overnight. I just mixed up some electrolytes and probiotics. Should I put some acv in with it? They will have a pool with fresh water too. Please help. Thank you!!!
