I've actually found that LegHorns tend to walk that way. I think that with their huge combs they don't see well on the side that the comb hangs over so its their way of coping with only seeing well out of one eye. If she has been that way for as long as you have had her I wouldn't worry about it.
I thought so. I was not to stressed. She will be seperated with 3 other sweet hens that wont pick on her. We are getting the second coop built tomorrow.
