Not sure if this has been answered before. I had 6 in the incubator and 6 under broody mama, all chicken eggs and all set at the same time. The incubator chicks hatched on days 19 and 20 (4 of them). Mama hatched 4 also on those days and then abandoned her nest so I put the last 2 in the incubator. It’s day 21 and no movement. One of the incubator eggs was moving and peeping earlier today but it’s silent and still tonight. Being that all my chicks hatched on day 19 and 20, is there a chance the others can even hatch on day 23 or 24 or even later? Not sure if I committed a no no but I candled them today to check for movement but saw none that I could discern.
