Just wanted to share...I have 6 babies due Wed. 3 silver pencilled wyandottes, and 3 old english, all bantams. I went in tonight to check the humidity and I HEARD CHIRPING!!!!! and 1 of the eggs was rocking alittle. With my first batch in Jan., I had my incubator in my bedroom. I was almost asleep and heard chirping. I thought I was dreaming (didn't know this would happen). I got up and went over, thinking I was nuts, then heard it again. Of course I looked it up on this forum and confirmed that I was indeed, not nuts (at least not about this). I was whistling a little while ago and they chirped again. YYAAAAAAY!!!!! Keep your fingers crossed for them.
