We are getting ready to build our coop. We are planning to build a coop with attached run, and will be painting the coop itself, but didn't want to paint the run. I am concerned about using a sealant that is not non-toxic, my children will be eating the hens' eggs and the coop is in the garden near our vegetables. I also do not want to use treated lumber. Has anyone used soy seal? http://www.amazon.com/Soy-Seal-Wood-Sealer-Waterproofer/dp/B0054653QG Are there other stains or sealants that are safe? Any other suggestions or advice? Should I just break down and paint the run too? Thanks!
