Eggs hatching - please help

[OnChickWatch]

It's day 21 and the first egg has hatched in the incubator, the chick is trying to stand and moving about but has managed to roll all the other (5) eggs to the edges of the incubator (they are in a brinsea which I have been manually turning eggs, nothing 'holds' them in place)

Was planning to leave the chicks in there til they hatching finished, but will this stop the others hatching now? Don't really want to open it unless I have to

It's a tricky one. You need to leave the hatchlings in until they're completely dry, otherwise they will get cold and quickly die, even under an electric hen/lamp.
If there's absolutely no sign of pipping from any of the other eggs, then you could quickly lift out the (dry and fluffy) chick without loosing too much humidity, esp if you can make the surroundings humid too.
The risk of leaving them in is the disturbance to the remaining eggs, and also the base of your incubator is likely to be slippy enough to cause the hatched chick to be sprackled-legged (where they stick out at right angles to the body), though I've not a Brinsea incubator.

We have a brinsea. we find that the eggs hatch out over a 1.5 to 2 day period after the first one pips. we leave them in the incubator for around 12 - 14 hrs after hatching to dry off and fluff up then move them under a lamp in a purpose made high sided box. if you do it quickly one of you picks up the chick the other removes the egg shells its come from with no loss of humidity. did the other eggs hatch?
