Please help! I am in the middle of my first experience with hatching eggs in an incubator! It has been thrilling and I can tell will be addicting! I have 3 chicks that hatched earlier than the others and are 1 1/2 days old. New ones are hatching today and the older 3 are pecking on them. They are even eating the egg yolk sac off the newly hatched chicks. Is there anything that I need to do about this or just let them go until the hatching is completed? TIA!
