I use easibed for my hens. Take the poo out every day and use maybe a bale a month for 15 hens. Top up bedding weekly. Works really well. In the nest boxes I use a chopped wheat straw bedding, tried using this for the whole house but it didn't absorb well and was tricky to get rid of (my hens have a woodchip enclosure so I just chuck the easibed outside for them to scratch around in).
