I pulled the 14 eggs Monday. I didn't notice any sitting until yesterday. I gave 12 of those away. Should I go put more in there? One of them came off the eggs this morning and out into run. The other one is still in there. They are a Splash Maran and BCM by the way. Dad is an EE.
If it was me I would give them some fake eggs or golf balls to sit on and then wait a couple days to make sure they are serious about sitting. Getting up for a short time is normal but if they are dedicated they will return to the nest....they will also stay on the nest at night instead of roosting.
I also usually move my hens at this time out of the egg laying nest boxes and into a nest where they won't be bothered by other hens trying to lay their eggs. At this time I am still using golf balls so I don't risk the actual eggs. Usually if they are broody they will sit tight with the nest full of golf balls I have given them in the new spot I have put them....but I know this is not always the case. If the spot they have already chosen is okay with you then you can leave them where they are.
In the meantime I would collect the best eggs I wanted them to hatch. I would put them in cartons in a cool room, pointy side down. It's okay if you take a couple days to collect the best sized and shaped ones and the ones from the hens whose chicks you most want to hatch out, like your best layers etc. Don't set any dirty or damaged ones. Decide how many you want each of them to hatch and save up that many eggs. The hens will wait. Remember half of the chicks will be males and you will have to keep them, find them homes or eat them.
Mark the eggs you save with a date or an X so later you can make sure none of your other hens lay eggs in the nest with the broodies. You want only the eggs you set for them to be in there and you want to set them all on the same day so they will all hatch around the same day.
If they prove to be dedicated then give them the eggs you have saved and marked and take away the golf balls or fake eggs (you might have to do this at night if your hens are aggressive about you reaching for their eggs).
Check daily and remove any new eggs you find that are not the ones you marked.
After 21 days you should have some chicks.
