I've got two eggs still in the machine but I dont think they will do anything....no signs yet and they are one day over! I only had 6 eggs in the Brinsea, the other four hatched but two died within an hour or so of leaving the egg...still in the machine. I dont realy know what was wrong. One lost a tiny spot of blood so maybe it had not absirbed the yolk completly. At least the two live ones are different from each other and realy cute!
