I have two 7 month old Toggenburg/Saanen wethers. At night, they are housed in a 9 x 9 shed with dirt floor. Of course they pee during the night and the straw I use as bedding get's soaked. Therefore, I clean out their area every day. I leave the door open to help dry the wet areas before putting down new straw. However not sure what to use to help with the urine smell and drying the wet spots. I was told to use Lime, but concerned that would be toxic for my boys. Any recommendations? Also, thinking about changing out the straw for wood shavings we have on the property from chipping slash, or would the goats eat it?
