5 yr. old Black Stars get watery feces. It may clear up for a time but comes back. They are molting now and one has died. None are laying but all are active, eating well and peppy. They are free ranged with chicken mash and scrartch available. I am wondering if these are symptons of poisoning as a neighbor on my East is very much against anyone keeping chickens even tho all of us around here take good care that that stay in their own yard and do not keep roosters. His complaint is that he has heard of chicken diseases that can be transferred to humans. He has been very vocal and mean but is not supported by all the other neighbors. Any help would be appreciated.
