I see you are in Florida... are you sure they are all chicken eggs? JK.
According to http://urbanext.illinois.edu/eggs/res17-layeggs.html it states "It takes from 24 to 26 hours for the egg to be laid. Even a good hen cannot lay more that one egg a day."
Maybe you have some neighboring chickens using your yard?
