So I have a large hen house with 28 hens and inside that a smaller pen with a rooster and trio of small hens and then across the yard a coop that holds at the moment 7 hens and a rooster comfortably and both coop and henhouse have large walk in pens on them. Then I have a chicken tractor that at the moment houses a rooster but will house the extra cockerels this year that equate to meat birds so it's out of the way... Long story short that's 42-43? Large birds and inside 2 brooders & 2 incubators and well it gets a bit smelly though we clean and clean and clean... So in the summer it's like 75-80 birds and it's hot and... Well what can I do to actually make it's smell much better- herbs- a special way to clean? Thoughts all appreciated...
