I had a question...I have 10 hens; 2 that are 8 months old who were laying 1 a day. Then I have 3 that are 6 months old and 5 who are 4.5 months old. As of now I have received no eggs!!! My older girls haven't laid since October! Whyyyyyy?? They can't be still molting? Can they? Advice people please!!
