My barred holland hen was laying steadily one egg everyday and was gaining weight great and was all healthy. Then about three weeks ago started losing weight drastically,n stopped laying cold turkey and developed a funky looking growth between two of her toes. The growth is a red color and has not gotten any smaller as i had hoped it would and gets la.ger every day. Her behavior, otherwise is completely normal(though extemely frightened at any movement other than her fellow chickens). Please help!
