Ok, I"m stumped on this one, hoping someone can help me figure it out 
Both of my hamburg hens had strange brown bumps/growth in their nasal cavity. One had it on both nasal openings, the other only on one. I've been watching it for a few months, and they don't seem to be in any pain or other health symptoms. Neither of the roos they each are partnered with have anything like this. They are being fed layer crumbles, some scratch once a week or so, household food scraps and treats. Same diet they've had for a couple years.
I got curious and picked one off each hen,and the weird thing is the part I could see, sticking out of their nose was brown and, IDK, almost wart-like looking?? But when it came off, the part that was down in her nose was bright yellow - yolk colored! It was about the size of a big pea. Neither one was happy about me doing this, but neither one seemed to be in any pain afterwards either, just irritated about being messed with.
There was no blood or drainage. It seemed like they started small and grew to fill their nasal openings, even stretching one of the girls nasal opening a big larger it looks like.
Anyone have any idea what I'm dealing with? I thought maybe they got a piece of food stuck in their nose, but it seems odd that they both would, and that it would stay there for months and get bigger. So I''m just puzzled. Any ideas would be appreciated!
Thanks in advance!!
