Yeah, winter is not good on the eggies...Patience is key. Often the winter can in fact prolong a young pullet's wait to lay her first egg. And of course, not all pullets begin laying at the same 'ol early 5-7 month age. I've known plenty pullets of many breeds and crossbreeds alike to lay anywhere from 6-14 months of age. If their time to lay is creeping into winter months, I usually have to wait a little bit longer. But not too much longer, don't worry.
