I have three Lavender Orpingtons that I purchased from a local breeder about six weeks ago. The seller said they were about ten weeks old at that time, so now they are about 16-18 weeks old or so. Can you all look at these photos and tell me what sex you think they are? I think the taller one from the picture with the three (the bird in the middle) may be a cock but not sure. (I am posting two more pictures of this chicken alone that may be clearer...it is a very tall bird!). Thanks in advance to any help anyone can provide.
