You need to finish what you started. The pieces you removed are a solid. You need to make the cut larger and remove the entire mass. Injecting baytril into the mass will not work. It is past the infection stage and hardening. If you do not remove the mass it will start on the other side of the birds face. You will make an incision under the entire lump. and gently squeeze it out. If you do it correctly you will get it out in one piece including the part inside the nasal cavity. I rinsed out the cut with saline solution and gave the bird the shot of baytril. Give the bird a 2cc/ml injection of baytril.
