I read up on chickens before we got our four girls this spring, and maybe I didn't remember reading about the shorter days slowing down their egg production, but I have 3 who are 7 1/2 months and still haven't laid a first egg, and one who started laying in September, stopped at the end of October (she went broody for a couple of days, then just quit for awhile) and just laid her first egg in over a month today. What is up with them? Do you think the other three could still start laying at any time or will they wait until next year? BTW, they look ready, red combs and wattles, one is squatting here and there. They go in and out of the henhouse and dig in the shavings very frequently, but they've been doing that for about a month.
