There is when the chicken has a pea comb and the blue egg gene. The genes are very close together on the genetic code, so they become linked. When offspring are hatched from a split blue egg layer with a split pea comb, the chicks that inherited the pea comb very likely inherited the blue egg...
Layer breeds are pretty useless meat birds though. It takes a long time to raise them, and you only get 1-2 pounds of meat. The cost per pound would be way higher than a cornish x, and who would want to buy an expensive, scrawny bird when they could get a big cornish for far cheaper?
These are my thoughts exactly. If the male chicks still have a purpose (fertilizer, pet food, ect.), I don't see how age of the rooster makes a difference.
Well... I do think birds from a breeder who cares about standards will have better birds than a hatchery. But I wouldn't discourage anyone from having or showing chickens because they have hatchery birds, especially not a kid who put a lot of work into raising a chicken.
But colored egg baskets are fun! And egg customers like it when there are more colors than just boring tan and white. Sure, the eggs just get eaten but they can look nice in the carton before they do.
How is that mean? If done properly, hairspray doesn't bother the birds. I agree spraying them in the face isn't a good thing to do, but not everyone does that.
The collars are cruel. I had them on my boys for about a week, and they did work to reduce volume. But after a week, their comb and wattles started turning purple (meaning lack of oxygen). To work properly, they have to actually CHOKE the rooster. Tried it once, never again.
