My frizzle has had diarrhea for some time, but no other symptoms. Now my bantam cochin has diarrhea too. My Polish does not. (3 chickens in all). They are all behaving normally. The Frizzle has recently started molting, but layed regularly until then. The cochin was broody FOREVER but is now laying almost daily. Their personalities are as normal as ever. The 3 chickens have a large space with bamboo leaves for litter. I let them out to free range a couple hours an evening and all weekend. The diarrhea is quite watery and smelly. Is it roundworms? Any suggestions???
