Hello!! So we are on day 21 with our broody hen sitting on her nest.. she has been very good. Rarely leaves the nest.. I've actually only caught her once or twice in the evening up drinking but quickly is back to nest. We did not candle the eggs as this is our first time. I did not know what I was doingor what to look for. I did not want to bug her. So now we're on day 21 and just checked under her and the eggs for any signs. So far no pips are shown. No cracks or holes. When do they usually start? When should I try to candle if no signs or piping ? Also how do I do it correctly? If nothing comes when do we sort of give up on the fertilized eggs?
