Is it normal??????`( african grey)?

What the hell are you feeding him all that crap for! People would die to have a parrot like that and you are feeding it that much junk! Get it on a good diet of roudybush pellets and fruit and veg STAT! In moderation it's ok but giving it 3 to 4 nachos with cheese OMG! honeslty! The birds body doesnt know what to do with it! of course it likes it but you like junk food too... do you ea that 24/7?! I think not! Get with it! No wonder you are experiencing so many irregularities!
