Opening the the egg tubs won't cause deformities are you sure you didn't have a spike in your temps? You really hit the odds making 7 males ouch. Last year I bred a queenbee to a normal and ended up with 6 eggs. All 6 were normals. Talk about hitting the odds lol Many years ago I bred a pastel to a normal girl. She gave me 11 eggs and 9 were pastels. Out of those 9 one was a female. Sometimes the odd gods just don't like you.
