I really need help with BEDDING in the duck houses! The house is set up with an indoor and outdoor section. There is a small opening into the outdoor part of the house and that is covered in open wire and the food and water are out there. So, theoretically, there is not much moisture that gets into the actual duck house other than the excrement coming from the ducks. SO, the bedding : I take shavings and put those down first along with a good dusting of DE. Then, I put straw on the top of that. I thought that this system worked well with my smaller specialty aztec ducks, but, with the bigger ducks (layers, pekins, swedish, khaki's, etc) this seems to not last more than a day. They completely cover the hay, no matter how thick I make it, with their poop. The shavings help soak up the moisture, but, they mash down the hay in a day. Within a few days, the house, which is ventilated, STINKS like cat pee to high heaven! I would have to add fresh straw everyday and once winter gets here, that is not going to be economical nor practical in any way. I heard once of someone mixing something under their bedding that took away the urine smell. The chickens have a bag of shavings dumped in their house and then I ad a little more and it can go for WEEKS without stinking or becoming offensive in any way. I usually finally clean it because I just feel like it is time! With the ducks, I can't keep up! Please...any thoughts on what others do would be great. I am in Vermont so it is about to get very cold here! I have them for layers and breeders. I want eggs, eggs, eggs, from them Thanks so much!
