I agree with igneriss. I got the impression they're like a duo/partners from the same colors, and you gave the man a little more tan skintone and a gold belt. Maybe you could give the woman a gold lightning barrette in her hair? I think cause we mostly see the head/face first, that would be an ideal place for adding a bit more variety.
I actually got a pair of white chickens that look very similar, and I did it intentionally, hehe.

The intent was to clue the reader in on Friar being "dubbed", cause he has no wattles(the hanging bits on the beaks) in comparison to Bress and other roosters, but I know many might not catch that detail and that's okay. Confusion is just part of the reading experience, especially if we read too fast in that scrolling format, lol!
