I am new to hatching chicks. Have tried several times with only one to two eggs at a time due to layers being young and not laying much. I have a LG 9300, struggling with humidity and have added bowls of water and wet towels, think it is now ok. Have two eggs in bator now, at day 21, no movement or chirping but one one the eggs has started in the last hour having spots on the shell that appear porous and also a ring around one end of egg that appears the same. Is the chick in trouble, or is this normal? Going crazy!!! as I have not experienced a hatch( they die between day 18 and 21). Please help.
