Today is day 20 on my eggs in my homemade incubator. Day 21 starts at 11 am. I've been checking every hour to see if there are any pips, but so far nothing. Of course, checking all the time is a habit I've gotten into the past 3 weeks, checking temps every hour. Anyway... when I first turned the incubator on, one of my dogs, Lily, showed a little interest in it because it was new. After the first day though, she hasn't even looked at it since... until today. I've seen her staring at the incubator at least 5 times today and she has even gone to sniff at it a few times. Could she be hearing chick noises that I just can't hear yet? Or is that just my wishful thinking that it means something will happen soon?
