My totally healthy girls include a flock of 4, the Australorp hen fine yesterday they went out and ate some grass and pecked around for a bit while I talked to neighbor. I normally keep them in coop ( its cold) or in the protected dog run attached, so no free ranging typically until yesterday for about 15 min.. I hope they did not eat something when I was not looking that is poisonous?? Not much available and they all nibbled the same stuff, mainly shoots of green grass. No other of the three other girls are affected.... So this is the issue, just tonight noticed a head tilt using one eye or turning head at weird angles to look at things, Her balance seems ok, eatting drinking ok, preening ok, talking ok, but definitely not normal head positioning and clear to me and my daughter too, so not my imagination. Appears to have normal looking eyes, no injuries or anything... It reminds me of head tilt in rabbits, if anyone knows what that is, but she seems like her balance and walking fine and she flew up to her roost ok it seems. Also, while checking her once tonight, ht I noted she has a nild tremor ( her head and comb moving rhythmically very slightly, I only saw this once.... Anyway this is NEW and just come up tonight, or might of been there this am, and it was just so mild, or I was not looking for anything so I might of missed it earlier today....Definitely neurological I think... HELP. I am not sure what happened and if this is going to kill my sweetest girl. What do I do? What might I expect, does this seem like the start of some clear cut disease I need to treat right away?? Again, all three other girls ( a Blonde comet, a New hampshire and a Ameracuna (EE) her sisters of the same age are not showing any head positioning issues. Should I take her to a vet in the am, its late now 10 PM....I am new at this!!
