I have 2 almost 11 week pullets. They are eating organic developer. I also give them treats during the day...cheese, watermelon, corn, scrambled eggs, leftover eggplant parmesan. They free range during the day. The other day i saw some white patches on the dirt and thought the kids threw out some oatmeal and it got wet..but today my DH saw a big pile of it..and i realized it looked like the other stuff..so when i poked at it.. i saw it was their chicken feed....obviously thrown up. DO THEY DO THIS ONCE IN A WHILE OR IS IT A SIGN OF A SICK BIRD? They are acting normal and seem happy. ANYONE?????
