Should I start adding layer feed to their bin? Should I expect to see certain behavior before they start laying (squatting, egg song?) They don't seem to be doing anything special yet. I let them wander my yard (within a fence) and they have a couple of bushes they like to hang out under. Should I keep them locked in the coop until they are laying in the nesting boxes? Or wait til the first eggs before I do that? The three that are 20 weeks old are Wyandottes (one Columbian, two Golden Laced). I have two EE's that are a few weeks younger. They won't be harmed by the layer feed, will they? Their combs are pretty pink - that's a good sign, right?
