I caught my "female" Welsh Harlequin a few minutes ago, because we were suspicious that "she" was a he, and "she" is, in fact, a he. Anyway, I noticed a sore on under his right nostril, on his beak. It is a slightly raised bump, and it is warm to the touch. There is a scab the size of my fingernail at the top of the sore. I am guessing he got his beak caught on the wire in the pen and it got infected. How do you guys think I should treat it? I was about to drain it with a safety pin, but I wasn't totally confident, so I decided to ask you. Thanks!
