    grrrrrrR    big chicken, i hisS At you!!!
Aside from that description there's three hints containingbase64-encoded data, the latter two tagged "Public" and "Private".  Ittook me a while to realize that three letters in the description whereupcased, spelling out RSA. Knowing that I've decoded the three hintsto files and used `openssl rsautl -in ciphertext -out plaintext -inkeyprivate.key -decrypt -keyform DER` to decrypt the ciphertext into thefollowing:

Visiting this page I got:
- A GIF with a chicken, drawers and anime girls- JS code printing out more hints to the console- Two hidden paragraphs:
    9 20 30 15 16 5 14 19 30 27 29 8 20 13 12 28    "abcdefghijklmnopqrstuvwxyz[]. "
Numbers and a string as long as the biggest number.  That can bedecoded with a bit of JS in the console:
    var xs = [9, 20, 30, 15, 16, 5, 14, 19, 30, 27, 29, 8, 20, 13, 12, 28]    var chars = "abcdefghijklmnopqrstuvwxyz[]. "    xs.map(function(x){return chars[x-1]}).join('') // "it opens [.html]"
Using my guessing skills I fetch another website:
    curl http://unknown-123-246-470-726.herokuapp.com/drawer.html
It contains a flag: `rtcp{ch1ck3n_4nd_th3_3gg}`
