I have a flock of about 30 birds. 20 of them are Plymouth Barred Rock and 10 are Black Copper Marans. When winter started the most of them would not roost inside the coop. At that point I was getting about 7 eggs a day. I thought that was good considering the shorter days. One evening some storms came through and they all where inside the coop, so i locked them in for two weeks. I thought this would get them to roost inside. That it did. But 2 of my 3 rooster started fighting until my BCM died. They have all settled down and they have been outside with an open coop for about a month, The fighting started after I let them out. Since i locked them inside the coop they have laid 0 eggs. We have had three weeks of snow and temps in the single digits with highs in the low 20's What can I do to encourage them to lay. I have lights in the coop and run that come on at 3:00 am and go off at 7:30am- Any suggestions?
