I think it fits the theme and I tried. (Edit I made something else that fits the theme better after the challange was over pixeljoint.com/pixelart/138395.htm)
Yeah I couldn't think of anything else, also thanks for the suggestions.
I like the head/face. I'd suggest trying more contrasting colors (the yellow/orange) and trying to challenge yourself with another light direction and it's going to be more interesting to look at.
Also this was small enough not to need a seaparate preview picture. Presenting the nest apart like this was unnecessary and I thought it was a sausage before clicking.If you'd actually done the part hidden under the chicken it'd make more sense.
