A new paddle made from high‐density polyethylene plastic has been devised for use in egg hatching troughs. This paddle is very safe as it will paddle properly through water and can be stopped easily when grabbed by hand. The plastic used to fabricate this paddle is 1/8 inch thick and cut from a drum with a reciprocating saw. New 30‐gal drums, made of food‐grade federally approved high‐density polyethylene can be purchased for about US$30.
