The Chosen Ones

Does anyone know what to do with the chicken head in chapter 4? The description said something like "there are 6 numbers, and 7 things, whats the 7th?" and then "one, two three, one, two three" and when i type in 1 too the chat, i got a thing that came up saying "-com1: hide evasion" and that's as far as i got. I've been trying to figure this out for ages now and its gotten me stumped.
