Ignorant question time: I have raised a bunch of pullets since they were day old from the hatchery a year ago. No cockerels - no crowing, no obvious plumage/body shape differences and I am pretty sure that they are all laying. This week, one of them crowed several times during the day (not sure which one)... not at night, not at dawn... and I thought to myself that perhaps a hen was being dominant or something... because it wouldn't be possible that I have a roo. Then I wondered... ... and the next time I cracked an egg, I saw a red spot in the egg yolk/white. I haven't had that before... is that evidence of a fertilized egg? If it is... how come my roo has been masquerading as a hen this whole time... why doesn't it crow... what the heck is going on???
