Hello, I posted a week earlier regarding my orpington, now I have taken new pictures a week later, with another younger blue orpington . The first two pictures are from my almost 11 weeks old orpington, really not sure male or female, can't see any saddle feathers yet, but is the tail growing any sickle feathers?? The last picture is of my 7 weeks old orpington that suppose to be a female, but somehow the crown seems bigger than the older orpington, or maybe the feathers around the crown is just shorter? Also the tail is longer. Please advise. Thank you.
