Mixed batch of chicks from Meyer hatched on September 9th. Order was only suppose to have 1 rooster (faverolles), but I suspect my Cuckoo Marans and White Rock may be male also. Thoughts?
Its still a bit young to tell for sure; I would post new photos in a few weeks. However, I agree with you that your Cuckoo Marans is looking somewhat rooster like with those thick legs, tall stance, and reddening comb. Your White Rock could be a rooster, too, but I'm going to say pullet for now.
Your Cuckoo Marans and White Rock do have rather large combs for their age, but the combs aren't so red and large yet that I think they are males. White Rocks are a fast maturing breed, so they often develop combs a little quicker. Post some more photos in a few weeks to have another opinion. As of now, I think its likely that you have two pullets.
Yes, it does look like your WR and CM are male at this point. If I were you, I'd give Meyer a call. They have amazingly friendly customer service and will give you your money back no questions asked, most likely.
I cant comment on any except the polish. I have a female and male polish, both are 13 weeks old. Yours looks like a female. The feathers at the top are full and rounded. The male polish are easy to tell early and have spikey head feathers from the beginning. They dont have a FULL set of feathers-look more like mohawks. So female!
