Actually I didn't want to open new topic couse it's related to another discussion but I don't want to jump in directly on it, sorry for additional thread.
My blue budgie is always so hyper he (actually both of ) took hormonal injections (3 times) and he seems fine I think But I always check his cere color. Not fully blue and sometimes less sometimes more brownish (to me). So Should I be worried I don't know.
I attached my both budgies pics. You can see the difference. Yellow one 's cere is blue and I think is ok, but blue's cere not completely blue What do you think?
