About 5 weeks ago I was getting 15 eggs a day out of some 30 odd laying pullets (older than 28 weeks). Then we had a severe cold snap and egg laying more or less stopped, 5 eggs a day. The cold snap ended and I was down to 2 eggs a day. Now I have a 31 week old pullet who has gone broody, I thought that only happened in their 2nd year... Any suggestions on how to snap them out of this? They get an 18% layer (non-GMO) feed, lots of fresh water, black oil sunflower-whole oats-scratch twice a week as treats.
