My Luna went into breeding mode in August, her cere turned brown and crusty etc. It has been 5 months and it is STILL brown and crusty. I was worried it was mites, but it isn't all inflammed, it doesn't look like mites, she's not itchy and the other 3 birds are fine, so, when will here cere go back to normal?┬Ąt=677d47b4.pbw
