I am getting anxious to have the last 7 of my girls start to lay. I have a Black Cuckoo Maran who is 18-19weeks old, has a very small comb and no wattles. Beginning to get a bit more red. My PBR and RIR layed at 19-20 wks. and had very defined, large red combs and wattles. What should I expect? I have a hamburg who is a week older and very little comb also, I believe they can be expected to mature slowly/lay later. 2 Standard Cochins are 20-21 weeks and only one has red comb or wattle, other is not even close, I understand they can also be later layers. 3 EE are also 17 weeks with pale, tiny combs, just hope somebody starts laying before the snow flies! Im impatient again...the 7 older girls are producing wonderfully.
