I would like to submit one more type of chicken expression (in addition to the two we have previously discussed). This hen looks neither outraged nor content. Not even "contentraged", an emotion that---let's face it--is probably apocryphal.
No, this hen looks like she is...brooding. Over her brood. Of chickens.
Turns out the chicken is the magic link between brood (the verb) and brood (the noun). This nerd-tacular insight is one of the most exciting parts of chicken-keeping so far.
