Tiny blood spots on egg

Well I make up a slurry of diatomaceous earth with water or poultry shield and a good slug of washing up liquid and really really slap it on the entire interior of the hen house in the Spring. It's not pretty but he hen's dont seem to mind. I can then touch it up as the season progresses/as needed. I also paint the perches with that old fashioned fence stuff that most of use cannot access anymore and soak the ends of the perches in it for a day or two for good measure. I then leave the perches out of the house for 6 - 8 weeks (I have a spare set) then slap on the DE slurry before returning to the hen house.

Frontline spray once every 6 to 8 weeks.

Hope this helps.
