The Combo is designed with staggered tiers, which ensures the birds optimum freedom of movement, in a way that no other system on the market can. Further more, the centrally positioned nest ensures, that the hens have very easy access to the nest. The Combo also favors the producer as the staggered tier design provides an unobstructed view of all tiers & the nest simultaneously. The Combo ensures easy access to the individual tiers, and the slatted area in front of the nest is by far strong enough to be used as a catwalk for inspection. The Combo meets German KAT requirements as well as EU requirements.
