We have 3 six month old RIRs, 1 five month old RIR, 1 five month old Black Australorp and 2 three month old black australorps. Of the oldest 5 (the six month old RIRs, five month old RIR and BA), only one looks remarkably different than the rest. None are laying yet, and none are even singing the egg song. Below are some pics of the "odd-ball". He (we think) has not crowed yet either, and none of them are putting on spurs. And a pic of the girls: Is there any way that the first one is just a "manly" hen? And why are they not laying yet? Thanks for your help.
