okay so my very small bantam has been laying on eggs for 19 days now but on day 17, 18 and today, i've noticed that when i get there she is wandering around the pen, when i check up on her eggs theyre scattered everywhere in the nesting box and they are quite cold, on day 17 i cracked one open to see if it was okay and it was alive (i felt so bad for opening it) so i left the eggs alone till today, i was scared they were dead but i think i heard one faintly pecking inside the egg... when i put the hen back on the nest she seemed to refuse to sit but after awhile she would stick to sitting, i'm scared these eggs are dead or dieing, should i incubate them? also some of the eggs smell, are they rotten? should i candle? any reason why she seems to be uniterested in her eggs? i really want these chicks to hate also on another note i have another hen sitting on a few eggs but they are a few weeks old about 3 weeks plus, i was wondering will they still hatch? should i put the cold eggs underneath her instead?
