Alrighty, here we go (if I made this too long, I'm sorry!)
Original idea, dated July 2021:
Friar Chicken originally a comedy, cause of the punny title.
Alec Tryon:
Originally not meant to be featured, so I wasn't concerned on drawing him that well. Now he's a main, and to this day it takes time for me to draw him.
Friar, the Chicken (my MC):
The second concept(below) is what I stuck with for a more serious story, rather than a pure comedy. Above is his first headshot as it appears in the comic, which was drawn a little over 3 years ago. This also established the idea of "halo" panels, to denote moments of focus/clrity, or just a headshot. Idk, it ties in with the religious theming.
For the record, I actually wanted to keep the rope and leg wrappings, but I forgot to draw them when I started the comic. I plan to gradually incorporate clothing/accessories on the characters to denote major changes later on.
Bucky and Gallus(right):
Not sure why Bucky's knees faced forwards, but I was trying to capture the dumpy look. He was originally all black, but I added red markings to give him a more distinguished role, as friend to the MC.
Gallus(right) was drawn very large in the beginning, but I shrunk him down, honestly because I drew him from memory, and forgot how big he actually was. His body also looks closer to an actual rooster in later version, and his scrawniness adds to his compensating anger.
Doctor Fowler:
"Plague doctor chicken" was all I was thinking with this. Didn't like his entire face covered, so I designed his real face and simplified the design of his costume - also, note his hat 
Bantee(right):
This is a Madrid Aseel, longer legs and taller than most other roosters I've made so far. Done some updated designs, but I am still happy with how he looks, just in a more refined style (you'll see him later)
Chickpea:
Serama Bantam(small breed), Nothing really changed about her design. She's cute enough as she is!
Nixworth(to appear soon):
Hadn't yet drawn this guy in comic, but I know that feather vest of his is gonna be a pain. Slightly overdesigned, but I'll see what I can do...
Gallus(again) and Chantecleer:
Chantecleer, the--Chantecler. Not much changed on him either.
