Some claim it is......was long 'discussion' on that in a hemp bedding thread a week or so ago.I use a full bag of Equine Fresh every time I replace bedding, and then top it with 1/2 a bad of Medium pine shavings bc the poop attaches more easily to it than fine pine shavings. I clean every 3 months, and I have a vinyl floor, so I don't need to scrub. I will also use clean leftover bedding to scrub any poo on the lower walls or corners.
There was a poor design to the 5 nest boxes (coop made for 12 chickens), so that they scratch out the bedding. I cut up two small entry way mats (new) to fit, and the carpet is soft and seems to suit my hens. They are a tight fit and they don't shift, plus they can be washed and put back when necessary.
The Equine Fresh is made of extruded pine mush and REALLY keeps down odors, and we know that pine isn't toxic to birds.
Anything else but sawdust on the pellets...wondering of maybe there's some zeolite(PDZ) in there too??
