Quote: eprinex is a dewormer liquid you put on the chickens, not on the floor. I'm pretty casual with my chickens, if you think about it, they even eat their own poop, or horse poop, or whatever they think looks good.!
I usually worm with Ivermectin, which Eprinex is a more diluted form of, twice a year. That takes care of anything like mites or lice, plus worms them. In fact, I have never found any on my birds.
I wouldn't worry too much about the chickens. Like I said, they will probably gross you out at times...to see what they eat, etc. It drives me crazy when I give them nice clean water, and I see them outside drinking out of puddles with horse poop in it, or their own run if it rains a lot....ugh
