I bought 3 pullets in June, they were born in April/May. One started laying in early September, the other 2 have yet to start laying. How can I get them to start laying? They've been fed layer pellets since I bought them. The two that aren't laying are a Buff Orpington and an Ameracauna. I built a full coop a week ago, and have been keeping a 25w incandescent light on from 4am to 8pm. I'm in VT, getting only about 12 hours of sunlight. Before that, were living in a chicken coop with no supplemental light. They aren't laying anywhere else, they're contained in a pen all day. How do I get these girls popping out eggs? Is there a way to force them to lay like 24 hour light?
