I am raising 4 chicks that were hatched in April, 8 months ago. The bantam and the Maran have been laying for the past 2 months. The other two, a Sicilian buttercup and a welsummer haven't laid anything yet and still look like hens, no cockadoodling or anything, so idont think they are roosters. Do these breeds normally take a long time to start laying, or to crow if they are in fact roosters? Thanks!
