One of my 4 month old runners sounds congested, making squeaking noises when she breathes. Her face is swollen. One eye is runny and there is a bb-sized lesion on her forehead between her eyes. It appears to be draining.
There is no drainage from her nares.
I did not see any signs of illness until this evening.
She has been active all day, free ranging with the other ducks.
Her weight is good.
I have her isolated and put Duramycin in her water.
Is this a sinus infection and what is the best treatment ?
Thanks for all help.
