Kinda. The chickens technically speak, idk, fowlian or something other than English, which I try to illustrate using a different style of balloons

I did have a written language, as you can also see in the image, but I had lost the 'alphabet' when I transferred the files to a new PC/tablet, so it's technically a 'lost language' rn.
Maybe best that happened, cause I had wanted to leave 'letters' in the chicken lang in certain scenes and spell out some secret code for the viewers to interpret, which sounded really cool, but I don't know what the message ought to be as of yet. Might revisit the idea later if I feel there's a good incentive to be made, and redo the alphabet too. Heheh, realized it's chicken scratch...
