I had to do this on a chick once and left it on 2 days. Took the tape off to refresh it and the toes were good so didn't need to retape. So for me I only had the toes taped 2 days.
I taped my chickens feet flat to a little wafer of cardboard. They fell off after a couple of days, and I replaced them. My chicken's feet never straightened out, but she is doing just fine with her funky feet (14 months old). Just make sure the tape doesn't get to tight.
I hope your chickens toes straighten out, but if they don't, things will be ok
What is the cause of crooked toes in chickens?
Most crooked toe conditions are either management or nutrition related. A lack of the vitamin riboflavin results in an inward curling of the toes and is called curled toe paralysis. Improper incubation temperatures will increase the incidence of crooked toes as will inbreeding. A few chickens with crooked toes (3-5 per 100) are not unusual. High yield meat-type birds will have more of a problem with crooked toes but this generally does not hurt the birds.
