Chirpy (young in this pic)
I brought my budgies two years ago. Their ceres are changing colour quite often (blue to a dark pink and back to blue again)Something they are blue and pink. They are in good health. Eating normaly and are active. I was just wordering if it was anything serious, and is there a way we can find they are male or female without DNA tests? This hasn't been a recent thing. (It has happened ever since we brought them) Any help would be apprecaited. Thanks!
