is it ok to use soy fed organic chicken for broth?

[Razmatazz]

i know you shouldn't eat the fat from chickens fed soy due to estrogens, but do they end up in the cartilage/gelatin? The chicken feet i use for broth come from chickens fed some soy..
does anyone know?

thanks

We don't

We are very careful with it, as soy is unhealthy for the chicken, so the chicken will not be healthy, therefore I prefer chickens that have had the freedom to eat grass, worms, insects and whatever they want.
