Do double yolkers porduce twin chicken?

[GreggsEggs]

If a double yolker was fertilized would/could it produce two chickens? And would they be Identical twins or maybe fraternal twins coming from two different yolks?
I sometimes get eggs that are 3x the size and weight of an average large egg, if hatched will it produce a larger chicken(like baby Hughie), than a large or smaller egg would?

Fertile double yolk eggs can develop two embryos but the likelihood of incubation being successful is extremely small. There simply is not enough room in the egg for two chicks to develop nor for them both to be able to pip internally into the air sac.

They would not be identical. Two yolks two differnet chicks just as if there were two shells. Large eggs with a single yolk do produce bigger chicks. This is not considered desirable in breeding, however. Eggs should be selected from your birds that are neither to small nor to large. At least that is what I read in my poultry book.

they would both need nuitrients and egg only has enough for one chick so only one would live
