This is the 2nd pullet in a year that has thickening leg bones. It is not the skin as in scaly leg the bones are growing thick and the pullet is small and seems to be stunted. She can get around but the legs seem weak on top of growing very thick. I cannot find anything that matches her condition all the pictures of rickets I have seen don't match. Rickets seems to bow or twist the leg this girl's metatarsus bone is growing thicker. Other than being stunted and underweight she seems normal and tries to get around with the flock. Any ideas of what could cause this? I thought it was a congenital defect with the last pullet but now it is happening again several months later in an unrelated pullet.
