Just thought I'd share a little info going on, on another thread regarding meal worms. A poster or two on another thread have noticed that when they feed their chickens mealies the egg shell color darkens and brightens. They have commented on this happening several times when they would run out of mealies to feed the girls a couple of days later their eggs would change color then when they would start feeding them mealies again the eggs would change back to the darker / brighter colors.
Anyone notice this w/ their laying chickens and mealies?
It seems that high copper content food (such as quinoa) might darken/brighten the blue/green egg color, and so I did some research and found out mealies are actually pretty high in copper (and calcium) content, so that could explain changes in the colored eggs (maybe) but a whole other chemical (from the blood not the liver) is responsible for the brown, so not sure how that is affected. Anyway just curious.
