A few weeks ago, I had noticed that one of my silkies (9 months old) started developing a lump on her beak. I tried to clean it myself, but then noticed that she started bleeding whenever I touched it. I ended up taking her to the vet, to which he prescribed medicated drops. We ended up quarantining her and cleaned her beak up and applied the drops until it finally healed. However, I noticed today that my other silkie (also 9 months old) started developing a similar lump. She is acting normal, and eating normal, however. I was wondering if anyone has any idea to what this could be? I would really like to prevent any other beak lumps on the rest of my chickens! Any help is greatly appreciated! Thanks!
