I have 9 hens, and most are now laying. Of my 9, I have 3 bantam cochins (TSC chicks), that are 36 weeks old. My black one has been laying for 2 months, she has even gone broody on me, but I broke her and she is back to laying again. One of my buffs has laid a few eggs, gone broody, stopped, but not laying again. This was over a month ago. The other buff has never laid an egg, and does not look like she is ready. Is this normal for bantam cochins?
