perfect! You will see, it will help! I had a friend with a hen that did the same thing. After one or two doses the hen was fine.I got some B complex vitamins today that can me disolved in the flocks drinking water. Can't hurt to give it to all of them. Tomorrow they will all get scrambled eggs with the shells made from eggs that are not up to par for market or hatching. They should get some B12 out of tho;se.
