We now know that my son has black cochins and white cochins. Can anyone tell him what color eggs these will lay? What color eggs will the australorp lay? What color eggs will the RIR lay? His grandma who passed away this winter left him her chickens. Awhile back she had chickens with blue feathers. There aren't any right now but he thinks he might want some. Can anyone suggest what kind of birds these might be? He says thanks!
