Oh.. thanks. We thought it was calcium so we started giving her the pill, after 4 days she started laying again (weird sizes and very white) then after about a week it started again, we did the calcium, and the same cycle repeated. It seems strange that she's not able to maintain the calcium...
Did you ever figure out what it was or what to do? I have the exact same problem. Pullets were bought from a pretty dirty place in Northern California (santa rosa). Not sure if we should kill the suspected chicken or not?
