This morning I let our rooster out as usual and noticed no problems. This evening when I got home from work and went to see them he was in the house and wouldn't come out. Eventually my husband managed to get him out but he was very lethargic and his comb and wattles have turned very black looking. Not spots like the avian flu pictures I have seen, just literally changed colour. Can anybody shed any light on this? Am I going to loose him?
