Rhea buys a total of 24 x 2 = <<24*2=48>>48 eggs every week.
Her son and daughter eat 2 x 7 = <<2*7=14>>14 eggs every week.
Rhea and her husband eat 4 x 7= <<4*7=28>>28 eggs every week.
So, the total eggs they eat is 28 + 14 = <<28+14=42>>42.
Therefore, the total number of eggs that are not being eaten is 48 - 42 = <<48-42=6>>6.
