I let my little red bantam hen (Not sure of Breed, shes a TSC special) Henny Penny hatch two eggs out after she FINALLY became broody. She hatched one of her own and she stole an egg from my australorp hen as well. Well after 20 days one chick was hatched by 6am, and the other shortly thereafter. The chicks are True Rose comb Dominique Roo over the Australorp hen, and then the Dom over Henny Penny, whatever she is. Both look exactly the same from what I can tell, the one was dry, the other had literally JUST hatched, but still appeared to be black with a head spot. ANYWAYS to the whole point of this post, according to head spot, dry chick is a hen, and wet chick "appears" to maybe be a roo? Will the head spot trick even work with mutt chickens?? Any thoughts?
