Hello everyone, My wife and I are new to raising chickens and bought 6 chicks (3 different breeds) back in April. They all did fine, but only one- the smallest chicken has been laying on a regular basis. The other 5 have not laid one egg, and here it is mid- November! They get good organic feed and snacks like oatmeal and scratch. Does anybody out their have any suggestions? I know winter is approaching and I don't intend to light their small coop, although I have wired it. Could it be that we have only been relying on layer feed. We have not supplemented them with oyster shell bits although I'm thinking I should get some. Suggestions? Thanks in advance.
