Wasn't sure where to post this .

I heard of one about brown eggs having harder shells, but not about nutrition.

Chickens have good colour vision and we found that white string was preferred to yellow, red, green or blue ones by chicks and adults and that monochromatic bunches of string (white or yellow) were pecked more than multi-coloured ones (Jones & Carmichael, 1998; Jones et al., 2000). It is unlikely that the attraction to white and yellow string reflected greater brightness and, hence, visibility for several reasons. The home cages were well illuminated, chickens can
discriminate between colours in near-darkness, and we would not have expected the observed increase in pecking at red, green and blue strings with repeated presentation if the chicks had found them difficult to see. Although inconsistencies often appear across studies in observed colour preferences, these probably reflect differences in the stimuli and experimental contexts as well as the genotypes and ages of the chickens used. Our findings are consistent with suggestions that chickens find blue food and objects aversive and that red may act as an unlearned warning signal that elicits avoidance (see Jones et al; 2000).

From Link below. Also offers info. on what sort of television programming they prefer (along with more germane info):
