We had just put eggs in the incubator when my dad passed away. We came home to find the humidity was down to 40%. I filled it with water and has been fine since. We had 2 chicks hatch on day 21 and 11 more hatch on day 22. We lost 5 of the 11. The chicks were becoming dry in the membrane and I had 2 wrong position ones. The last 2 I had helped with an air hole in the air sac and had wrapped in the warm wet paper towels and they both hatched out during the night. Of all the chickens that hatch they are all silkies but 1. My Orpingtons are not hatching. I candled them. (With our cell phone so maybe not the greatest light.) There are masses in the eggs. I looked for pips and didn't see any. I listened to the eggs but don't hear anything. So I did the float test and have about 10 eggs that passed so I put them back into the incubator. These eggs are my expensive silver lace and blue jubilee eggs that I purchased. Is there anything else I can do? Since there are masses in the eggs could they be hatching slow since the humidity wasn't idea?
