Hi there! New here; but I had a few questions about my families budgie Gilbert. We've had Gilbert about 4 years now from the local pet store. His beak turned blue when he was young, but has been brown for at least over a year so I suspected I might have been mistaken on the gender! I'm housesitting and noticed recently that his feet have a bit of a blue tinge at the top. They're not cold to touch and he's more perky lately if anything (more chirpy with the neighborhood birds anyway). His beak as well has a greenish tinge to it. I plan on getting a few new variations of perches tomorrow and a new cuttle bone. But wanted to make sure I shouldn't be more concerned and passing any information along to my family? Thanks in advance!
