last month, I got three laying hens ( domineckers) that are about a year old. The first week I had two eggs. Since then, four weeks now, I have not had one egg. I am in the South so there is decent light but it has been regularly in the 20s at night. I feed them laying feed and supplement with lots of kitchen scraps. I had rhode island reds this time last year and got eggs all winter, not as many in the summer, but I still had a decent supply. I am really starting to worry. Is there anything I can do?
