I have a broody Silkie sitting on a clutch of eggs and I am growing increasingly concerned as even with the candle and tap test, I still didn't hear any peeping or see any movement. I heard in cold climates they can take 4-5 extra days to hatch, so I will wait and am glad to have such a dedicated hen who will wait with me, but I would like your thoughts on it and would like some advice regarding on anything I can do to help.
