This is Oliver. I was hoping for an Olivia. So now what I am hoping is his sister I am fearing may also be a rooster. I was pretty sure I heard both of them crowing. But I am holding out an ever fading hope. Is it unusual for siblings to develop at such a different pace? Oliver got much bigger much quicker and also grew wattles much faster. Even tho in the rest of the pics you can see streamers do you guys think the 2nd 3rd and 4th pics that I could possibly have a pullet??? Thanks for any input.
