I have an 8 month old BA pullet who started laying within the last month. About six weeks ago, I noticed her poops were watery, sometimes seem to be just water, and are projectile. She does not have soiled feathers around her vent and nothing smells bad. I'm feeding layer feed (in the process of switching from 16% to 21% protein due to a picking problem),grit and oyster shells, ACV in water (1 oz./gallon), a little BOSS as treats, and she has free access to coop/run/and slowly disappearing grassy area. I orderd three different kinds of Probios, Bird-Powder, Probios, and Multidophilus Powder which has L. bulgaricus L acidophlus, and B. bifidum. I have watched her carefully over the last few days. When the other chickens run for BOSS treats, she stands around as if she doesn't know what to do. She might eat two seeds. She also does not eat as much layer feed as the others. Sometimes she will go up to the feeder as if she's going to eat but then just turns around to go somewhere else. She drinks LOTS of water. She seems sensative to the actions of some of the chickens, as in thinking they might do something to her but I've never seen her pecked, picked, or been made to move. She doesn't run into anything. (At one time I thought maybe she didn't see well.) She likes to be out in the grass scratching around and she pecks around in the run. Yesterday, I noticed she would stand on one foot for a while and then switch and stand on the other. She's having no difficulty walking/running. I've given vitamins/electrolytes in the water for the last two days. I don't have a clue what to do now. She's not energetic this monring. Any suggestions?
