Chickin Fairy
Songster
Thank you! I ran out of PDZ, so I'm reordering. My coop floor height is at my waist level, so I get a good sniff when I go in for eggs. Thank you! That's good to remember.That's what I use chickin fairy, just sprinkle a handful in when it seems smelly. It is heavier and larger in size so less likely to become suspended and breathed in. Everything you put in the coop is basically at the chicken's respiration level, so things like dust, ammonia, strong oils like cedar, and other stuff affects them quite a lot.
You want to check down at chicken level for odors, not at human height, by the time they rise up they are usually very strong at chicken level.
