I used a mason jar with the dish cloth over the top when I had little chicks. I order from azure also. It's half the price of ordering from Amazon. I also order different kinds of feed and I mix them all together. Sometimes if it isn't used up in a while it will get a very strong smell but it doesn't mean it's bad. But it can definitely stink up the room. I try not to get it that badYa everyone keeps saying that they had not problem but I just can't risk spoiling more of the food. It's too expensive and I have to order it monthly from azure standardI waisted several days of feed that first round. Went into the trash. I think it was too warm in my garage or something introduced some bacteria to it (maybe a bug). My garage is insulated but I'm not fermenting in the house until I have some glass jars to use. That way I can use cheese cloth on the top and keep it up off the ground. I had issues with fruit flies getting in my fermented feed when I was doing it to grower crumbles because I just had the bucket kid sitting on top of it.
