I have had my chickens about a year now. Have had four die in that year (don't know why) and two in the last month. I did find a worm in run so I have wormed them all. I have one chicken that wants to say in nest and when I make her get out of box she rubs her beak on ground and is a little mean to other chicken. I care to my chicken every day fresh water, food and clean housing. I also talk to anyone I can about raising them and normally everyone I talk to say they have never had any problems. Starting to think I should have got a pet rock. Chicken live all over the world,can my problem be our property? Maybe something in dirt or Indian burial ground.
