LOL... oh there have been plenty, but you know, they get lost..
Ok... You can keep them in the cartons, or take them out... Your choice. If you take them out, the new chicks will play soccer with the remaining eggs. I take mine out.. but that's just me, and that also depends on what bator you have and the room inside.
Get your Humidity to 50-60%
They don't need food until you take them out. They can stay in the bator for 48-72 hours.. but I don't usually keep mine in there that long.. It all depends on what type of bator you have..
Brinsea Mini, or Octagon, you can take them out AFTER they dry up and fluff up. Any other bator I would wait till the hatch is over. If you do remove a group of them, make sure that there arn't any pips, or zips happening while you do it. No mater which bator just open the top long enough to remove the chicks and spent egg shells..
Have your brooder ready to go with the heat lamp, shallow dish with water (or a chick waterer) Make sure it is shallow enough that they won't drown. New chicks should be warmed to about 100 degrees, then you can drop the temp by 5 degrees per week until they are fully feathered. You will know if they are too hot or too cold. Too hot they won't stay under the light, but around the light, too cold and they will huddle under the light and make a really loud peeping sound that's just not their normal peep. It will be loud and shrill.
As you take them out, just dip their beak into their water. You only have to do it once, and they will know where to get water. You can use a small lid, or sprinkle some crumble chick starter on a towel for the first day. They will figure it out. I generally put a towel in the bottom of my brooder the first day.
