I've got 19 cornish x from a hatchery, either Mcmurray or Meyer, i don't remember. Anyway, I gave my buddy 10 at the same time. We're feeding them the same feed, from the same feeder (he made me one), and the only difference is his range in a garden, and mine range all over the freaking place. Anyway, he processed his birds last thursday, and they were HUGE, like 2 of mine taped together kind of huge... I brought 2 of mine down, my biggest 2, to add to his on processing day, just to kind of get a feel for the processor guy... so I went to pick my 2 out of my friend's freezer, and his are giant and distinctly yellow, and mine were smaller and pinkish. any thoughts? i don't understand how they can be so different in size and color too? aren't we all the same color on the inside?
