Normal hatching is 18-21 days Gazza, looks like the eggs are blank or dead in the shell, possibly caused by the moving and settling in at yours. Hopefully you'll have better luck next round
I have a 6ftx3ft aviary attached to my stock loft which goes all the way to the ground with a concrete base I put in myself. I then have a frame of 2in x 2in covering the base of the aviary with a couple of support batons which has 1in x 1in heavyduty wire attached which is placed on the concrete floor and I just lift it up on its side when I clean the aviary out.
I had almost the same a few years back sammy only there was no hens involves and had 2 yearling cocks took up a nest box together and raced out the season for me. Lost both of them the following year from the channel when I had them paired to hens :(
