Um, they're chicks!
No idea of the parentage but my wife says that they could have become a chocolate sponge or a batch of lamingtons! We had purchased some free range eggs for baking as our girls weren't supplying enough for our needs and having noticed a bullseye on each of the yolks I "rescued" 2 dozen of the eggs and put them in an incubator. 3 chicks so far but we'll see what tomorrow brings.
good luck I hope you get more hens than roosters.
