[newbie ducks]

so a few weeks ago a bunch of muscovy ducks were poisoned & my friend saved this guy life, however his poo was yellow then green & had a little bit of yellow again, but now green again. he showing signs of wry neck this is what she gives him, is there anything else she can do?
she said still no progress with control of his body and neck , though he moves his neck well he has strength in it his ones eye is still closed he is bathing and preening himself , eating and drinking . He is very strong physically and mentally . He is also very smart . I see him cleaning himself and flapping his wings as if he just went swimming in his cage area and very independent when it comes to eating and drinking and as soon as he sees me he stops

he a wild duck unfortunately a bunch of all ages had died all in a matter of a few hours, even dead ones were floating in the pond & around the pond areas. looks like someone dumped something in the water or fed them and FWC came took one to test it, but they never got back with her as to what killed them all & she been trying her best to get any answers from them. the vets around her will not treat Muscovy & avian vets are too far away. she giving him giving him the activated charcoal for the poison which she done for about 2 or 3 days then stopped his poo was running yellow then went to solid green for about 2 days then had a bit of yellow with green, high amounts of niacin, vitamin E and selenium as well as nutria drench. He didn't like her duck food. she also has a female adult Muscovy as a pet, but she keeps her separated from him. I told her to try him on the dumor for all stages crumbled duck food it's high in protein my wild ducks love it in between them free ranging. And I mix just a little bit of rooster booster in water for mine. I told her try the rooster booster. He is eating & drinking on his own but has a hard time with his neck the way it is. And one of his eyes are still closed. maybe she can try to make him a little neck brace help support it? Idk.
