Change in feed question

[haunani]

My younger set of girls finally hit the 16week mark right as I ran out of starter crumbles, so I was able to switch the whole flock over to their layer pellets, which is also soy-free.

Here's my question. How long do those laying need to be on the new feed before their eggs would be considered soy-free?

I would think ten days should be enough for that . It depends on how much body fat is present .Soy can be stored in body fat longer than muscle . So it could take longer to completely cleanse the body fat of soy .It also depends on the amount consumed during the time soy enrich feed was used . If you are selling eggs as soy free I would wait at least 20 days just to be sure .
