Every day when I go in to clean my chicken coop, I find that the shavings are soaked where the older girls (1year olds) lay at night. There is usually poo around as well as to be expected. Just the shavings soaked as well as the boards. I have read the chickens don't pee, so to speak, so do they? From what I have read, chickens urinate via their poo, as the white stuff, but this is different from that. There is no color to it. I've noticed it more lately, I just started giving them OACV. I never used to have wet shavings and wet boards, what could have changed?
