thanks for replys thought i should follow up , someone else may have this problem . called county ag agent after posting he asked if feeding had been changed ,to which I replyed that we had gathered our field corn two weeks prior to having the white pullets go lame ,and had been feeding maybe six or eight ears per day to red and white pullets. He said white pullets are smaller body high egg producers and can suffer from calcium deficiency before other birds, so we stoped feeding the corn, which by the way is white field corn if that makes any difference, and all the lame pullets began to mend. put the first sick one i found back in the flock today 11/24 she is doing fine has even began to lay again. they have all been on laying pellets since aug and have had a feeder full of oyster shell since begining to lay first soft shelled eggs. But i noticed that the pullet that was worse than the others refused to eat the oyster shell while she was seperated from the others no matter how i gave it to her. i have been throwing a handfull now and again out to the others ,they eat it like its a treat. so i guess the county ag agent knew what he was talking about. Thanks again for the replys
