Has anybody ever heard of wormer causing chicks to hatch with missing toe digits or nails? I know of at least 2 people (myself and another lady) that got hatching eggs from a flock that has all normal feet. The parents had been recently wormed with some kind of chemical (not DE). Could this be the culprit? They are from 2 separate pens, different varieties even. I had though tit was genetic, but the only common denominator is feed, medication and environment. Any input appreciated.
