Wrong i placed my eggs in containers from walmart and was able to place 2 in each hovabator. For the ball python eggs i used a rubbermaid 128 oz 1 gal large rectangle container.Measurments were 13 inches long 9" wide and 3" deep this one held 7 eggs with room for one more.In the same hovabator i had sterelite container also.Measurments were 9" long 6 and a half inches wide and 4" deep,it held 2 eggs with no more room left
