First time brooder here! Silkie's eggs were fertile, placed under her on Saturday. Yesterday (Monday) 3 out of 6 hatched! But today I checked under her and all three had "Cracked" and one I had to discard because it was apparently not alive. Two are still under her and one is half out of the shell, been that way since at least this morning. She nipped at me this evening so....I am not sure if the other two will make it. The one I discarded had a foul odor. Worried these two will get turn sour (if they haven't already) and draw fire ants. Any advice? Just leave nature alone?!!?!?!
