The last time I posted I put 12 eggs in bator that were started by a broody that was given chicks from a hen that would not take care of them I did not know when she started sitting on them but today I had my second hatch of Cochins. Of the 12 eggs 3 were cracked by hens toes shells seamed thin. 1 was almost round had to candle to find air sack. So 8 went to lockdown all 8 hatched in a 14 hour span. This is a DIY bator with rocker turner and by next spring it will be a hatcher only plans are in the works for a 3 shelf cabinet. I'm hooked
