Perchie girl, I think it was, did a little tutorial for us on the other FF thread about the meanings of the numbers on the bottom of the buckets and there are certain numbers that are considered safe for putting food into, some that are ideal for putting food into, and some one shouldn't put food into. I'm pretty good with the safe for putting food into buckets I got from Lowe's but I didn't have to knock myself out with worry over searching for places that will give away a bucket. Some will, some won't, some are not allowed to do so due to liability issues. In the broad scheme of things it's easy for some and some just stress out about getting one when they can't because everyone says they should or their chickens may suffer from it...but we all are eating foods every single day that are filled with the junk in our food supplies and gagging on this one gnat while swallowing the mule of that food supply out there is inconsequential...it's making a mountain out of a molehill. Sure, if you have one, use it. If you do not, don't stress it. You are slowly getting poisoned anyway...even the carpet fibers in your home and the plastic your car's dashboard is formed out of are putting off toxic gases at all times. I don't think your feed bucket will beat them to the punch on getting you dead.
