My hen has been sitting on guinea eggs for 23 days. I had to put numbers on the eggs as other guineas and chickens would take advantage of poor Ms. Liz and lay eggs in her nest. We are within 10 days of hatching. Since ms. Liz is a gorgeous black Australian chicken should I just let the eggs hatch? Will the Guineas or other chicken hurt the babies? Need help. Also can I handle them right after the hatch? Thank you
