Hi everyone, Just after some advice regarding a possible worm infestation. I have recently taken over the care of 2 Pekin duck drakes. Over the past couple of days one of the drakes has started to cough. All other behaviour, appetite and stools are normal. I haven't yet wormed them (though perhaps I should have) and I am concerned he might have gapeworm. I must admit to being confused as one post I read said that gapeworm doesn't exist in Australia- is that even possible? I have some kilverm (levamisole) left over from worming my chooks. Would this kill gapeworm? Or just the ones listed on the bottle? If this won't work what should I use (instead or in conjunction). Thanks for all the advice - I don't want to see my boys get sick.
