Hello! I am new to this forum and I need help finding out the sex of my new Budgie. I bought my Budgie Cloudy from pet smart on July 1st, judging by the stripes on their head and their black eyes they are probably >5 months old. I thought they were a boy but now I’m confused. When I got them they’re cere was blue like in the picture, maybe darker, but for a time they had a very pink cere, and now they’re back to blue. I’ve been reading up on the different ways to tell but it seems that when they’re young it’s hard to say for sure and I won’t know until they’ve grown a bit or are at breeding stage. I’m worried of introducing them to the flock of 3 males because they would be the only female if it turns out that way. I appreciate any feedback! Thanks
