Apparently the breeder we got our crooked tail Buff Leghorn is not very selective about their genetic breeding program! This is the condition the chick was shipped by them!Wry tail in chickens - very interesting, this is what I found online. Never gave it a thought before, I must check mine to see if anyone has this also.
