N F C has given you some good links to where you may get some expert advice. I too am not an expert but agree that it looks like twins.
I hope you enjoy being a BYC member. There are lots of friendly and very helpful folks here so not only is it overflowing with useful information it is also a great place to make friends and have some fun. Unlike non chicken loving friends, family and colleagues, BYC’ers never tire of stories or pictures that feature our feathered and non feathered friends
Hello there, and welcome to the big, happy BYC family! I am so glad you joined us, please make yourself at home. I hope you will enjoy it here as much as I have!
