I ordered, among other things, 4 maran pullet chicks and 1 roo. Theyre nearing three weeks now and of the five only one is getting wattles in. His legs are a little thicker, and his comb, while not the biggest, is still big for a 2 week old chick. You suppose its safe to assume thats my roo? I also have the same number of Light Brahma's with one roo. Is there a trick to telling them apart? I have one thats the heaviest and has the thickest legs compared to the others. Its kinda silly to take pictures, because besides those tiny differences theyre all the same.
