My Cayuga mixes are supposedly 21 weeks, they are supposed to be cayuga x khaki campbells The lady i got them from said they started laying already which made me question their age. We have had them for over a month, they head bob and mate with my drake but nary an egg has been layed. What is up? We have just started getting colder weather this week... they eat flock raiser and free range. No hidden nests, if I can find a single chicken egg nest in 7 acres of woods I highly doubt I wouldn't find theirs , besides they stick pretty close to their pool.. maybe venturing 2-3 acres to forage. What is up with my hens??
