I have to disagree with this IMO i think it starts with the parents lacking key vitamins and minerals,when the chicks hatch they lack the sufficient amount also and at the rate they grow if they do not receive sufficient amounts they can develop this condition as they were born with this shortage from the start .......................................................... i got my greens and they were on 18% i saw several birds with twisted tibia even brought one home, mine were eating feathers so bad i bumped their protein levels up to around 25 % and have kept it there and they stopped, now i have just one that is doing it again but not for lacking anything i think she is neurotic as it only happens at roosting time no other time.anyhow not one of these greens developed twisted tibia with the protein increase,And here is another thread where @DylansMom helped me before, https://www.backyardchickens.com/t/915084/100-hatch-rate-on-shipped-eggs/130#post_13969568
You should check the protein level of your feed, it shouldn't be more than 18%, too much protein caused the twisted tibia to mine.
I have been feeding protein levels 20 to 25 percent for years young and old and never have i seen this happen here and i have hatched 100's as well as raised and sold 100's .
