I currently have 5 eggs right now in my Brinsea Mini Advanced incubator. Today is day 18/19 and I have seen movement from 3 of the eggs. Should I do a water candling test on the two eggs that haven't moved? One of those non-moving eggs has a hairline crack in it (It was there when the eggs arrived in the mail, but on candling day 8 I could see the embryo moving inside it). I don't know if the water candling would hinder the cracked egg. Should I wait until they have hatched to check the non-hatched eggs in water? Also, when should I take out the turning tray and put down the paper towel? It is still turning the eggs, but I expect it to stop automatically tonight (5/13/2015). I read in the incubator operating manual that I need to fill both water reservoirs once the incubator stops turning the eggs. Since I am seeing movement from them already, should I fill up both reservoirs now even though it is still automatically turning them? One more question, would paper towel or smooth top plastic shelving liner be better to put down inside the incubator for the chicks? Sorry for all the questions! I just want to make sure I am doing everything I can for an optimal hatch. Also, I don't know if certain breeds hatch earlier than others, but the 3 eggs that are showing movement in the incubator are an Easter Egger, a Sulmtaler, and a Bielefelder. The 2 eggs that have not moved yet are Jubilee Orpingtons. Thank you for your help!
