Sinus Infection Gosling

[Age-of-Goositude]

Don't know how it happened but I have two older Goslings with sinus infections. Lump on either side of their beak. Baytril is on it's way ordered it yesterday. I got VetRX and they had it overnight and all the swelling went down but it's coming back one boy has more labored breathing than usual aside from VetRX and baths what else could I be doing to keep it away and comfortable till the antibiotics get here?

PS rhey are threeish months old
