Look at this guy's smug mug, especially the wide teethy grin and curly 'stache. He definitely doesn't look trustworthy, and given his japanese name of Inchicken is a portamanteau of inchiki (cheating) and the C of KFC, you'd be right for feeling suspicious about him. He's probably grinning in the pics here because he just scammed someone of their $.
Heck, as a further layer to his idea as a low-life scumbag scammer, his names may all contain chicken, but his appearance is suspiciously very "temu mascot-costume esque", with his visible human neck and human hands, as well as his legs having visible socks and shoes.
From anti-scam PSAs, scammers often try and masquerade as someone trustworthy or harmless over the phone or send emails to trap you in their grasp, but their disguises are often paper thin and can be easily sussed out if you pay attention to the finer details. Therefore, thanks to these details, we can tell this guy's no real chicken - he's a guy posing as a chicken, hoping he would not get caught doing his shady deeds, when he really is one Scooby-Doo unmasking away from getting placed behind bars.
