The yellow fat was from older birds. The new breeds are raised in six months and never mature. The best chicken soup is from old hens. Their fat is yellow and they have to be boiled down to make them tender.
The new breeds are flavorless and have no muscle since they are raised in windowless warehouses. They are factory raised for uniformity and efficiency. The eggs are even worse. Fresh chicken and eggs are a world removed from the factory farms.
Without the intention of highjacking a thread, if you have never tasted the meat of a wild turkey, then you don't *know* what turkey should taste like.
Your first impression is *WOW*! So this is what turkey is supposed to taste like. Wild is good.
Carry on.
