The coolest thing happened with my young ladies! Well, in my opinion anyway.
At 6 wks old, they've gotten pretty cramped in their brooder (rain is prohibiting coop building so we're behind). I have a small area full of cranky, smelly chickens so on a whim, I tossed in a long sprig of rosemary. This morning, they're calm and quiet!! Also, the smell of rosemary overpowered the poo stink. I'm a happy chicken mommy today!!
Cool! I'm setting up a big herb garden for the coop right now. Hope to harvest and dry enough over the summer to be able to toss a handful in the bedding on a regular basis.
