Thanks everyone, for a moment there I thought the hens where dying!
I've been wondering what happens that make them produce offsets! The chicks I planted where takin off the hen on the same day, they where all pretty much the same size and have been in the same container ever since, just one has produced an offset and its not even the largest one! Its also starting to mound! Is there a secret something that triggers offsetting? Can it be forced?
This little baby is my favorite atm, it was one that was very small and I didn't know what to do with it so I just threw into a tiny pot and left it!
