Cleaning the coop

Before the hens come we was going to give the coop a good clean as its a recycled shed that we had to put together, was going to give it a squirt with the Jeyes fluid what strength is strong enough but not to strong to cause harm to the hens.

Hi
Does it not say on the tin what dilution to use?
A good thing to do before your girls arrive is to give all the nooks and cranny's a painting with the diatom slurry, you can find out how to do this if you search in the search box above.
Good luck
