I heard it could be something serious like Aspergillosis but I took it to the vet and he said if it is that there was no cure, and he gave me antibiotics which would get rid of any infection if it's there (the antibiotic is called Baytril) there doesn't seem to be much improvement after 24 hours of taking the antibiotic :/ I heard that putting the duckling next to a hot shower to breathe the steam so I did that today but still no change? I have no idea where any places that sell probiotic or duck supplements to get them for him so they can't be given to him and I don't know what else to do! The two are inseperable and it would be awful if one died! Please help, does anyone know what I could do? They are being fed chick starter crumbs suitable for ducklings and always have heat and water, any advice would help! Thank you
