Precision Pet Excelsior Nesting Pads: Precision Pet Excelsior Nesting Pads provide cleaner, fresher, and more hatch-able eggs through moisture absorbing technology. The moisture absorbing technology works by pulling moisture from droppings which fall to the liner below. Excelsior Nesting Pads then create a more sanitary nesting environment, by separating eggs from chicken droppings. Chicken eggs used for both consumption and incubation must be kept unsoiled by surrounding waste. Excelsior Nesting Pads also assist with faster egg gathering, by encouraging chickens to lay eggs inside of nesting box and by decreasing the likelihood of eggs breaking on an otherwise hard surface. Precision Pet Nesting Pads are sustainably sourced from 100% Great Lakes Aspen shavings and are made in the USA. Excelsior Nesting Pads fit inside Precision Pet Chicken Coop nesting boxes and most standard sized nesting boxes. Size: 13”(Length) x 13”(Width). Bulk Pack of 10.
