I have had silkie's for a little over a year now as a hobby. Love them! Great pets! However one thing is really troubling me. When I have a hatch off there will be Days before all the eggs in the nest hatch. Back in March I thought it was probably due to the weather and Temp changes but I have had the same problem all summer. I just had a hen hatch off 8 but it took 11 days from the first one hatching to the last. Luckily I was able to move chicks to a bantam that had just hatched off and she took the chicks. I feel like some of these being late is because i suspect another hen was getting in the nest and laying eggs after the original hen had started setting. But it doesnt explain all the other hatches and even on this one there was 48 hours between the first chick hatching and the second chick. Is this common with silkies or does anyone have another explanation?
48 hours is not too uncommon, but if they take longer than that, then its likely that another hen added to the nest. You can mark eggs under a hen with a permanent sharpie marker (anything less will rub off). Then you will know if any get added.
I date the eggs under a broody, and also draw a big circle on the fat end of the egg and color it in. That way its easy to find, without having to bother the eggs.
