Wow! Thank you so very much for sharing your success story!
Hubby & I have Comments/questions:
Our coop is also Ft Knox, like yours. Rats would have to spend a long time and much effort to chew their way in, unless they’re packing Dewalts.
The girls don’t have a covered run, just a large, simply fenced in pasture, not critter-free at all. They free range most days out of the pasture.
Do the hens need to remain in the coop during the entire 3 day cycle?
Also, we have a few (we assume rat) tunnel holes in the pasture near the feeding areas. We have not found the other ends.
Would the ammonia be damaging to the other wildlife that frequents their pasture at night, such as bunnies and skunks and possums and barn cats?
Those critters either climb or dig their way into the pasture, or simply walk through the fence.
Is one goal to make sure the ammonia won’t get into their pasture at all? Is that why you said to have it drip on the outside of the run?
Should we also consider spraying some ammoni into the tunnels & then plugging them?
Thank you so much for your answers.
