can a chick lose its 'spots' ?

[spish]

i originally posted in the genetics section yesterday but it seems to have been over looked so im going to ask here


i bought 6 poulle de bresse chicks yesterday, (3 days old)..it was dark when i collected so didnt get the best look at them (only light was a small heat lamp)
so anyhow i chose 6 and the guy threw in a freebie so i ended up with 7


got home and put them in my brooder. and thats when i noticed 2 chicks have black on their head (one has 2 spots the other has 3 spots)

i rang the person up and asked was he sure they were poulle de bresse. he said he was...but theres chance they got mixed with his Bresse van Louhans or Bresse van Bourg (sorry dont know the english names)
ive been googling pics but cant find chick pics of these 2....but im guessing the chicks would be mostly dark, not white with 2 spots of black?

i rang the guy again this morning and asked did he have other chickens, the guy said he has no other chickens apart from the three bresse sorts.
he also said its possibly the 2 will lose the spots when they feather out and still be beautiful white poulle de bresse chickens.....is that even possible??
i paid a lot of money for these chicks and am feeling a bit....well, conned i suppose is the word. my chicks could be mutts/crosses, not what i paid for

Yes, a chick can lose it's markings- mine all lost their "chick markings" when they were growing in their adult feathers. But if your asking whether they lose the spots while they are still fluff, I dont think so. But my chicks were EE's and wyandottes, so mabey other breeds do that?

Well, I am not sure which breeds you are speaking of, but I can tell you that my chicks look very similar to the one you have pictured. They will loose those spots and be a solid white chicken.

Several white chickens are actually silver, which can express with black spots. But not many chicks look like their adult counterparts so I'd guess they'll be all white when grown

so it is possible they are the other type of bresse? (known as zilverpel here which means silver coat) thats wonderful to know thank you
