Lately, my chickens have been tipping their waterer, then wallowing in the muddy puddle that results. They look like a bunch of hooligans when its time to come in! Is it a good idea to put a very shallow pan of water in the pen for them? I move the 10X10 pen daily. Also, what is the best way for me to tell if theyre using the portable dust bath I made for them (out of a big, shallow roaster -- creepy!) I put dust and DE in it for them every day. Thanks.
