I got my first 8 hens in June, they were all around 3 months. My Blue Laced Red Wyandottes are by far the slowest maturing, but they are now around 6-7 months, and one looks so much different than the other two. I was under the impression that by 3 months gender would be obvious, but I'm not convinced. JayJay is much bigger, different colored, differently feathered than the other two that I have. At first I thought it was just cross breeding, but now I'm thinking she might be a he. Is it possible to have a late blooming rooster? No crowing, all three have kind of still had more peeping sounds than anything until today, and JayJay seems to have a more growly voice all of a sudden. What do you think???
