Added 1 tablespoon per gallon to the waterer.. One in particular was doing the something stuck in the craw dance.. I've tried before thee.. Bring them in the house.. Feed em' oatmeal and scrambled eggs. They recover but became reinfected.. had to put one down. SAD.. My daughter a vegan, my fault. It was a joke.. at four years old isn't.. She said, "You mean you are feeding them to themselves!" Okay.. So this time.. though it is probobly the other.. I put one table spoon of baking soda in their waterer.. No more sour crop.. She is eating. Running amuck and follows me like a puppy.. Egg production increased and shells are definetly stouter and heavier in weight.. and it is aproaching winter. I wouldn't do it all the time.. Something to do with salt content.. but it worked this time. Happy chick, happy life. Any thoughts?.. but no dreams or visions. I've already seen the writing on the wall. Thanks.
