Yikes!
I created my own odor problem! Silly, silly woman!
The chickens were finally getting to bare stems in the bermuda grass portion of their chunnel. I know how tough bermuda is, so I thought, "I'll just water it and throw a little organic fertilzer down, spray it with seaweed, and in a couple of days it'll sprout right out!"
Please, DO NOT try this at home!!!!
What was I thinking? Watering the ground under the bermuda runners brought out the...um...err...uh...."piquant bouquet" of chicken manure.
Prior to that, it was a dry, odor-free run.
I guess I'll have to let the Bermuda die, and just use my "growing" frames. They aren't working as well as I had hoped, though; I think the situation is just too shady for things to sprout and thrive enough to grow fast.
