After just 3 years my goat's stall floor is disappearing. The whole barn is 12' x 12', the one stall is 12' x 6'. I have one doe and her 3 kids. We built directly on the dirt, which i now realize was a mistake, but spilt milk and all that. I usually do deep litter, but this year the flies are a real problem so i started thinly bedding the areas that get peed on the most and by the stall doors where rain can come in during a bad storm and then sweeping the stall out each day. Well, since April I've effectively removed about 3 - 4" deep of the floor. And I'm still battling wet spots and flies. I've been putting Sweet PDZ down, and it helps, but have used up a $10 bag in 2 weeks. That's not sustainable here. I need to add something affordable to level out the floors, but don't know what. Builders sand comes to mind as that won't biodegrade. I looked for dirt, but can't afford what i need, and don't want to put down the cheap stuff i've found. I've found ground pine bark, but that will degrade soon in our heat and humidity. Will putting barn lime and sand down cause a crust to form that will be more stable than our sandy soil? After i get it built back up, I was thinking of putting down stall mats and doing the deep litter over that in the Summer and Winter, but I'll have to save up for a bit to afford the mats. If anyone has been through this and has advice, I sure whould appreciate it.
