Hi! Do you hear the chicks peeping in the bator the day they hatch or before? My last hatch, I heard one about 5 hours before it hatched. But it was the only one that hatched. I had a horrible hatch last time. Right now, I am going on day 21 with silkie and bantam cochins and I was wondering if I should be hearing them in the bator yet? I don't hear a thing yet?
