I hope I haven't done something wrong! I just read in another post that one shouldn't use the powdered sweet PDZ because it can cause respiratory problems. Our local feed store doesn't carry the granular, only powdered, so I bought a 40 lb bag. Two weeks ago I cleaned out my girl's coop: scrubbed it down good, put down a fresh bale of pine shavings, lots of DE and about 20 lbs of powdered PDZ. Was this a mistake? Should I remove everything and start over? Also, I'm wondering if anyone uses powdered sevin (the stuff us use in the garden). Someone told me they use it in their coop and on their chicks - a very, very small amount. I sprinkled a tiny bit in the bedding (maybe a tsp in an 8X8 coop), but not on the chicks. Advice will be greatly appreciated by this novice chick mom.
