Onyx, Reba, and Tiny are pullets, April is a cockerel. How many pullets do you have? One rooster per ten hens is a good ratio. I would just pick the nicest one, honestly. You might want to keep a few for a while until they mature more and show their true colors. April I would not keep if he’s...
Ollie and his friends look like Black Copper Marans. Marge I’m not sure about. Penny is an Olive Egger. Erma is an Erminette, and your only pullet is Princess, who is probably an Easter Egger. :)
