HELP!! This rooster is new to us. We went out of town to come back to a new friend. I have looked around the neighborhood to see if he belongs anywhere and haven't found anything. We hadn't planned on keeping him but my kids and I already love him! We named him Mr.C. He definitely feels welcome here as he never leaves and comes to us when we are outside. Got on the back of my husbands truck cocka doodling away! My knowledge is nothing!! I bought chicken scratch for him and we are building a coop to get some hens. BUT I noticed this black stuff on his comb and I haven't a clue what it is. Attached pictures. We can't pick him up yet and I don't want to chase him to scare him. So if anyone can help me that would be awesome!
