I currently have 3 clutches in the incubator. The first was laid on 4/27/10 it is expected to hatch on 6/27/10. This is a normal to spider breeding. 6 good eggs. The 2nd was laid on 5/20/10. Expected hatch is 7/20/10. This is a lesser to sprider pairing and there are 6 eggs. The last one was laid on 6/10/10. Expected hatch is 8/10/10. This is a pied to pied pairing and there are 5 eggs. With my pied I noticed that the pre egg shed was on may 1 and she didn't lay until June 10th so 45 days about. The others were less than 30 days.
