Eggs hatching minus 6 days and counting

Here are the 4 out of 6 remaining eggs that im incubating. I have left 2 Speckled Sussex, 1 chamois Owlbeard and 1 brahma (may be buff or black)

These are in our homemade incubator

 They are due to hatch next Thursday, May 3rd but may be a day earlier or later. I stop turning them after Monday to give the chicks a chance to orientate themselves and get ready to break through those shells and say hi.
Im going to candle them one last time tonight just to check they are all okay and that the air sac is large enough for them.
I love doing this every year its so exciting waiting for them to hatch.  This time next week i could be a chicken grandma too.
