Do all Wyandottes have a rose comb, and do all rose combs have the little spur growing back? I have two 24 week old blue Wyandottes who have very red combs, but aren't getting the "spur." (My 22 week SWL is developing it) One looks like a wide pea comb, and the other is less wide, but has always had a little pointy bump on the top of the comb. They're big and fluffy, much larger than my SLW of the same age. Just curious if I should expect an egg until the comb is complete.
