My Black Copper Marans has a softball size crop... I don't know whether it's a problem or not. I notice that it is spongy sometimes and hard other times. Life has been a bit crazy here, but I'll try and check it in the morning to see if it's spongy. She is a bit strange - She's 9 mos old and she's only laid about 5 eggs at 8 mos old and they were giant size, almost double yolker size. Her comb is nice and red and it doesn't seem that she's in distress. Would like to hear about your ideas on this one... please!
