There was a small core and a lot of liquid. When I made an incision it practically spurted out and continued running down my hand for quite some time. It soaked a gauze pad.
Yep, I gave pills orally 2x per day. I started the same day or the night before I removed the bumble, if I remember correctly, but that was due to an error on my part. The duck healed fine and has not had a relapse.
