I'm thinking that one of my 4 week old Welsh harlequins has scoliosis. I've given them brewers yeast in the chick starter since birth. Lots of peas and dandelion greens. They have had vitamins in their water a few times. Because since birth I've noticed something "off" about this duck. Hes the one that was malpositon in the egg and peeping away from the air cell and hatched 2 days after the other duck. Hes always been really weird doing a flip when he gets scared. Walking in a circle till he falls over. Now hes starting to look noticeably different. He looks bent right at his wings, runs a little sideways, body looks short from the side, right hip seems to stick out . What do you all think. Is scoliosis what I'm dealing with here.
