These are in a Brinsea, so to me, it's not as easy to open as the styros were. Those I could do 1 handed, this one takes 2 people or you need to take the whole cover off, set it down, take out chicks and put it back on.With that many (styro bator?) I'd go ahead and quickly remove them... got a spray bottle of warm water handy? Pull them quick, give a spritz or 2 along the sides not directly on the eggs and close her back up... but that's just my opinion...![]()
