My chickens haven't laid an egg since Sept/Oct. I have Bielefelder chickens, LOVE THEM! I have about 27 hens, 3 roosters note that 16 of the hens are 6 months old. I have one hen that gives me about 4-5 eggs a week recently.
My first thought was my rooster was killed in front of the hens I believe by a fox or hawk. I couldn't find him for a week but the hens knew where he was. Then my chickens started molting. I also switched their food to higher protein content, in the past that has aways worked. Not this time. I have do not want to give them extra light because I do want them to rest over the winter, but in the past they have never stopped completely.
At the same time I just finished building a 12x16' new coop with a beautiful new 12x19' run. They do love the new dwelling and now most of the flock won't leave the run. These chickens have 10 acres to free range, they only use 1 acre. But now they are afraid to leave the run and the doors open. I see no predators for what that's worth. Any suggestions?
