All sorts of different stuff to absorb chicken droppings , how about having a water proof coop floor and wiping it clean once a week? Is there any problems with this I read Some things dont absorb Amonia as much as others so having nothing will absorb none however adiquate ventilation shud be ok right? however maybe cold for the chickens having enough ventilation, will amonia be produced straight away or after more than a week of the poop rotting down? Planning having a hen house for 6 rhode island red hens, with a water proof 4' x 4' base + Nest box, with two 4' purches inside another thing would like to know whats the Hens favorite thickness of purch to encourage them to purch rather than walk in their droppings.
There is a system called Deep Litter Method. if you are unable to get to your coop but once a week then that would be the way to go. As long as the coop is water tight it's self.
I am sure you can do a search here on BYC and find out how to do this method. I am doing something similar. My bedding is dry and fresh smelling. As for burning their feet yes it could happen if your litter is always wet. The poop from my girls dries up very fast so no burning. Also with this method I do use "Sweet Pdz" it also helps to dry everything up quickly and keeps the ammonia smell to nothing.
I don't need to do much with my system. I just add more bedding as needed along with the PDZ. I do 2 full cleanings a year, I remove everything and start over.
Chicken poop is good for your chickens as long as it is dry....the poop builds up their immune system to fend off disease.
I use pine wood chip bedding from my local TSC I purchase the Sweet PDZ there also (It's for horse's)
As for water...I am installing a rain barrel and piping water to Drinker cups.(they stay cleaner longer) I am not collecting rain water to fill my barrel as I have a shingled roof (too many chemicals in them to collect water) I will be filling it with the water from my well.
Good luck
