Welcome! While keeping goats and sheep together is possible, I wouldn't recommend it due to their different supplement requirements. Depending on where you live and the breeds you plan on getting, the goats may require free choice minerals that could kill a sheep.
from Central Texas! I have no advice on the sheep and goats (hubby won't let me have a goat "YET", lol) As far as the chickens go anything within reach, they will destroy unless it is wrapped in fencing.
Hello and welcome to this wonderful site full of great ideas and suggestions. I hope it all works out well for you and I can see why each group of animals would need to have their own enclosure since their feed needs are all different.
The fencing around the compound is almost superfulous because goats, sheep and chickens will each need their own confinement system while the flowers, vegetables, compost and worms may only need protection from the goats, sheep and chickens.
How about the fish and the ducks? I ask because they would need pond(s) and the excavated material from pond construction can be used to fill the raised beds.
Start by considering the topography (if there is any). The goats, sheep and chickens all need good drainage to keep it from turning into a mud bog.. Raised beds and compost can go almost anywhere.
