I know I've read on the forum and in articles before that many people use it in their coops. Today we were in Tractor Supply and I was ready to put a bag in my cart and my husband said it might not be safe for chickens because there wasn't a picture on the front of the bag along with the other livestock. There was a broken open bag nearby and he thought the texture was of the sort that chickens would try to eat. Can anybody give me a convincing answer to this? With all the wet weather we've been having this week, the chickens have been spending more time in the coop and when I opened the door this morning there was a slight ammonia smell. I cleaned the coop and put in fresh pine shavings, which helped. I've also read somewhere that a small amount of cider vinegar in the drinking water helps with the ammonia. I had been using that but have slacked off the past month. Will the cider vinegar in the water hurt the baby chicks? They are 3 weeks old now and have been mingling with the rest of the flock (with their mother too, of course).
