I have 11 hens-mix of breeds (RIR, BR, RP, BCM, EE) they are just about 20 weeks old (except for the Marans that are almost a year) and Nobody is laying anything. The Marans laid 1 egg each when they arrived (about 2 months ago) then had a moult, so no eggs since then. Now the little girls are all grown up, and nothing. They normally free range, but since much of my yard is heavy brush and woods, I have been keeping them in their pen for the last week (I figured they may have been laying somewhere else) and nothing. They get layer feed, scratch, vegetables/fruits and oyster shell calcium. I love them and all-but heck, we got chickens in the first place for some eggs! What could I be doing wrong?
