Have two Polands and I think they are both laying (due to two distinct sizes of eggs). The most exciting thing is that I have three Plymouth Barred rocks and one of them (all from the same hatching but one looks more mature with her comb and wattles and cheeks a lovely bright red) hay layed. I thought they might wait till the spring! I have been weighing the eggs and the first one was 43g. The fifth one a whopping 74g!! Is this normal?
