Kelly
I know how upsetting it can be, and very difficult to explain to a child.
You could sit the kiddies down, and tell them : That there is a special place over the Rainbow Bridge, where little birdies sometimes go....... A little funeral, sometimes helps children get through these things.
I'm sorry Kelly, that's all I can say. One could search endlessly for explanations, and answers, but in the end, it makes no difference really.
I'm not sure what went wrong. It could have been anything from lack of warmth, some sort of an infection, a digestive issue, something in the air.....
Personally, I would let them try again, and I wouldn't make a big issue out of new eggs and so on with the kids, untill babies pop out of the nest.
Have a good day hon, and be good to yourself
