My current group of pullets are just now approaching POL (they're at 20 weeks). Surprisingly, the RIR beat the Black Sex Link to it, and has been laying for a few days now, but everybody's doing the squat. The BSL is nesting, but is also showing common signs of broodiness. I know it has been selectively bred out of most commercial breeds (esp. BSLs), but is it possible/heard of for a bird to go broody right at POL before laying her first egg?
