We slaughtered our first round of meat birds last night. We had 7 roosters and 1 hen that we slaughtered. The roosters were all large, healthy birds with healthy innards. The female, on the other hand, had large amounts of visceral fat...probably 3x as much as the roosters. All of her internal organs were heavily encased in fat. Her liver was a brownish color instead of the reddish brown. Any thoughts as to what might have been wrong with her?
