I just put my pullets in a new run next to the older girls. They are just 2 days shy of 4 months old--three easter-eggers and a speckled sussex. Today I found a smallish blue-green egg in their run! I think it must be Cleopatra, who has a much more developed comb than the rest. I haven't noticed any pre-egg behavior such as squatting, nest-making etc..It is sooo strange! Should I continue to feed them starter/grower and just add a dish of oyster shell? I've got to make a nest for her--I am so unprepared--Is this just a test of the system, or will she continue to lay? This is like not having sanitary napkins ready....
