Quote: Hi GaryDean26! This is a great photo. You can really see the rock in her. For me, I think her bottom line is too curved (Rock-like) to match the CL description well, but other than that I think she looks more like I envision the Legbar hen than looking at a lot of the pictures I have seen of Leghorns. When I popped over to the Ohio show pictures ChicKat posted, the White Leghorn Hen they have pictured is much fuller bodied than what I have become accustomed to seeing--which are hatchery quality for the most part. So some of my perception may be tainted by the quality of the stock pictured.
I am not a fan of using the Leghorn as the type reference for the Legbar for the very reasons you have listed--most especially the comb, the back and the size. After looking at silhouettes of the various Mediterranean breeds, I came to the conclusion that you can still have a Med type without Rock influences and be of a very good weight and that with some differences, the Andalusian seemed to be a better reference for the Legbar, should I want to look at other breeds.
http://blueandalusian.com/american-standard-perfection-blue-andalusians/ I think for me the biggest difference that is important between the Andalusian and the Legbar is the description of the legs, with the legs of the Legbar having a shorter thigh thus not looking as tall/stilty and the tail angle of the Andalusian is listed at 40 degrees above horizontal instead of the Legbar's 45 degrees.
