Hi. One of my older chickens has a problem lately and we dont know what it is. Her symptoms are Swollen feet, diarrhea (its squirting out of her at times), weight loss and she had not been acting like herself. Sheveould stand on one foot in the backyard. When she sees me come out she comes running though. We just put the apple cider vinegar in ber water and we brought in the house tonight. Does anyone happen to know what is wrong with her.
