We have nine free-range chickens (two are Buff Orpingtons). They are approximately 5 1/2 months old and eight of them have been laying eggs for the last month. Everyone seems normal except for "Ester". She is a buff orpington that has the following quirks: -Constantly moving and turning head as if she can't see things too well -Runs with a stagger like she isn't sure when her feet will touch the ground again after she lifts them -Very skittish until she's caught and being held -No eggs, underdeveloped comb When she was a chick she often slept alone in the corner of the box we built for them. When we moved her to the coop her head tilted all the way over to one side and she acted dazed and we thought she was badly hurt. Her head was fine but she still has quirks and gets lost and can't find her way back to the coop at night some times. Is there anything I can do to help her? I just want to know more so that I can help her now while she's young if I can. Thank you!
