my chicken had her toe broken in a rat trap two days ago. theres a little blood spot near the base of her middle toe and she is walking with a limp. i've been puting neosporine on it but it looks a little green. is this just blue bruising on a yellow foot or gangrene? she eats and drinks like normal and her toe is not visibly deformed (not a crooked toe) although it is a little swollen. how can i help her? thanks
