My chicks were due Sunday, I still have nothing, When I candled at day 18 there was movement in 8 of my 9. I was so excited. now there is nothing....No pips no movement I did the water test lastnight and nothing, I candled this AM and these are pics of just 2 of the eggs, but I saw no movement and no internal pips either.....are my babies dead??? how much longer do I wait???? thanks!
