A chicken will lay more then 10 eggs and hatch them all - so even in a nest they must be viable for more than 10 days. If they are stored under ideal conditions - at home that is probably the salad drawer in the base of the refrigerator - an egg remains viable for upto 3 weeks, perhaps a little longer. Most aunthorities say they must be tuned at least once a day during storage but I never bother and eggs stored for over 2 weeks hatch fine.
Guinea and chicken eggs can not be refrigerated and stay fertile.

How long it takes to boil diced chicken pieces will depend on the quantity and size of the diced chicken. The typical cooking time would be an hour over a medium heat for a pound of diced chicken.

I am not sure where to get fertilized pigeon eggs, but why not look into getting chicken or duck eggs. You can usually get them from a local farmer for free as long as you promise to return the young after they hatch. You are getting the same experience for free, or next to free! And Yes, chicken and duck eggs can hatch in an incubator.
