Hello and I am new to raising chickens. I just noticed today all 3 have a large lump on their right breast. They are eating, drinking, pooping and acting ok so any clues what it could be? They were born this year. Also, my rooster stopped crowing. I try to get him to crow by crowing at him but he just stands there looking at me. The 2 hens will cluck when I cluck at them. Any help on this would be greatly appreciated.
