I rescued Pogo from the RSPCA about 3 weeks ago. I think he's a boy but there's a bit of brown on either side of his nose and my other, definitely male budgie, treats him as if he is a girl i.e. mounting him and pruning and feeding My other budgie has a bright blue cere which is shiny and vibrant. However, Pogo has a dull blue cere which is turning brown?? It's definitely not a discharge.
Thanks in advance,
PS. Charlie (the other budgie is fine) if anyone is reading from my last thread.
