I've always done shoes or tape when they were just hatched or right when an issue began. We had one chick hatch Friday with twisted toes (faverolle) and I made a little shoe, which she hated, passionately but yesterday was day 3 with a shoe and no more twisted toes.
I am still working on the sway leg that she and another chick have, that usually takes longer.
Can you unbend the toes on your chick still? Or is there too much pressure because that is how they have been? I have had parrots that I have bought that have had a toe twisted under and although it looked funny, it didn't impact them in a negative way but parrots fly most places, they don't walk so not sure what to tell you.
I am not that experienced with chickens, lots of experience with parrots so I am sort of doing what worked for me with them. I am sure someone more experienced with chickens will have some advice.
