No worries at all, my responses are often delayed too. :) You were still pretty quick though!
Hmm, I'm not sure what animations to suggest yet - but with this chicken being relatively large compared to some pixel art, I can't help but imagine it could potentially play a role as some sort of boss chicken. Maybe intense angry flaps (maybe while flying) causing a gust of wind, but I'm sure I could use the existing flapping animation for that. Maybe a quick 360 spin while standing, to hit the player with its tail.
I could add a couple of angry eyebrows for if/when the chicken gets mad, though I also like the idea of the chicken just being completely oblivious to causing difficulties for the player, so maybe the eyebrows should only appear after provoked/attacked by the player. Or maybe just during the angry aggressive flapping or something.
However, I don't want to sway your creative direction too much if you already had ideas in mind! Did you have any thoughts for more animations? I could tell you what I think sounds cool if you like, or just throw some more ideas off the top of my head.
Thanks for asking for my input!
