[Summerashlee]

Hi I'm new to the site and new to keeping/Hatching chickens I set 8 eggs 23days ago. By day18 only 4 of the eggs had signs of development and lots of movement so I went into lock down I candled them today no signs of movement 2 look like something is floating about moves when I move the egg think i may have lost this batch any advice would be much appreciated
