Good work.
Mine too. I was dreading a long battle from previous infestations in the cardboard egg boxes I had in the carport for my free range chickens. I caught all 10 of them, including Sam, and gave them to neighbors.
I removed a 2' x 2' area of the thickly thatched grass, about 2" down to soil, and laid down 1/4" of green sand that I happened to have. I then sprinkled Seven 5% on top of the sand. I also puffed-dusted the egg box with DM. Within two days no sign of mites. The girls are back to jumping up on my lap, shoulders, and even my head. #64, she's the jittery onelowest in the pecking orderjumped up on my lap and let me pet herthe first time ever. More significant, she did it while #61 and #62 were already on my lap. (I banded the four chicks with leg bands so I could tell them apart when they were younger).
I'm almost positive that the reason they got mites is because the last three areas that the 8' x 10' tractor had been on was heavily thatched grass and they simply couldn't get down to soil to bathe. The first month the tractor was always on dirt-grass ergo no mites.
Today I'm going to prepare a new 2' x 2' area and just add a layer of green sand and move the tractor over it, and see what happens.
Eggs any day now. I showed them an egg to let them know what's coming up/out. All they did was try to peck at it. So, I added two more floors to the egg box, the one slanting towards their entrance and the other slanting towards my cleaning-egg-retrieving drop-down desk-lid type door. Now the eggs should roll and drop down to the lower slanted floor and they won't be able to peck them.
