Strain the coconut water into a freezer-safe, airtight container and place it in the freezer, uncovered. Chill the coconut water for 30 minutes then seal the container and transfer it to the refrigerator. Pour the strained coconut water into an ice-cube tray and let it freeze for about one hour.
The most light weight and efficient chicken tractor is made from a wood frame with chicken wire around the sides and the top to allow for freedom of movement and fresh air to come in. Never put mesh wire on the bottom of the tractor because the chickens need unobstructed access to the soil.
Re: Digging a big hole 12x12x10 will be a job for an excavator and not a tractor w/hoe attachment. The tractor w/hoe isn't going to have enough reach to do the task you are preparing to do. If you are looking to get a good square hole with good vertical sidewalls, its not really a job for a novice. Sincerely, Dirt.
