hi my ducks are now 6 weeks old and happily living outside, I noticed today one was sitting down a lot more than usual.just picked her up and had a look and there is blood on the underside of her foot, its got a cut on it. I wiped it over,then swished her foot in clean water.she can walk but isnt doing so as much. what else can I /should I have done. the cut isnt really deep but is more like a slit. is there a spray i could get instore for another such emergency. will she be ok?
