Hi, this is what worked for me, I have a showgirl that was having issues , we figured from a head injury, he/she would put her head between between legs walk backwards and do flip flop as to say. I did a combination of a couple things. took a vitamin E capsule 400 I E put a hole in one end and opened chicks beak squeased couple drops on back of tongue , sqiurted rest of capsule on top of chicks grain mixed it in with a toothpick just on the top of grain. took cod liver oil and did a couple of drops of that and also bought vitamin B complex and did couple of drops of that. My showgirl I think was around 6- to 8 weeks old. the showgirl was in with 2 other chicks. the more my showgirl got stressed the more he/she would go into the flip flops. i did this for 2 weeks once a day, the second week I noticed less of the flip flop and walking back wards the 3rd week I stoped the cod liver oil and did the vitamin E every other day for like a week and a half and the vitamin B. So far so good he/she is not having issues at this time. I would say time and recovery would depend on what is going on with the chick and what is causing it. hope it works out for you.
