I have one duck infected with botulisim and I know she is probably going to die, but what are the best ways to prevent my other chickens and ducks from getting it. I am changing the bedding and water. I am isolating the duck, who's symtoms are paralysed/shriveled legs and weak neck, she's also not eating but is drinking. Am also cutting extra ventilation holes in the coop. Any way you can help would be great. Thanks in Advance.
