I have a Japanese bantam that went broody. The first set of eggs she sat on for 3 days before another hen booted her out. So we moved her into a private suite and set 5 eggs under her that she hoarded. I have a few questions; 1) Do broody hens know if the eggs have gone south? 2) I was told that bantams set for 19-21 days for a hatch - true? 3) Do hatches happen typically at certain times of the day? 4) The eggs came from multiple hens - with 9 hens, I imagine 3 roosters got the job done? She is such a good little girl - she is very attentive and only gets off for about 5 minutes a day. Your help is greatly appreciated.
