Today I was given a small mixed flock of chickens and there is an OEGB roo that has what I believe is wry neck- it seems to get around fine if it does not see you watching- I saw it drinking and eating ok, but when you get close, it drops and starts twisting its head around on its back. I have the flock in quarantine before I introduce them to my flock. My question is this just a genetic defect with the one bird or is this something that could be commutable to my flock. I feel that I should cull this bird but would like some input first. All birds are 2014 hatch and appear to be healthy except this one roo- its a shame too as he is a beautiful silver duckwing color...the other OEGB roo is nice but not as pretty as the one with the neck twisting.
