I have 5 black-bellied whistling ducks approximately 18 months old. One of them has started sneezing repeatedly in succession. 10 times in a row. I also noticed that it's (I have no idea if it is male or female) whistle has suddenly changed from exactly like the other 4 to a higher pitched and rough sounding whistle. This is new from today so I'm hoping if it is something bad I can catch it quick.
I live in an extremely remote location without access to a vet. BUT I do have a quite extensive med kit on hand.
I have available to me:
3 sulfas injectable
Oxytetracycline 50mg/ml injectable (this particular type can also be administered by mouth)
Worming meds of 2 types, fenbendazole and pyromantel
And one last detail, I noticed 3 days ago that this duck had a slight limp. It's foot looks totally normal but it does try to wriggle away from me when I probe the upper leg. I don't know if this is in any way related.
I have come to this forum many times for help and am eternally grateful for the help I receive. Thank you in advance!
