Welcome to the forums.
You have
alot going on.
Land Size=half an acre
Soil=Sandy, bottom is more compacted clay.
Animals= Geese, Ducks,
Chicken
Manure Production Area= Houses 2 horse+10 goats (during the day they live offsite on 2acres)
Before doing anything extra I would start of with the foundation aka the soil.
Soil
Earthworks like swales and
berms even if you only have half an acre.
Carbon, I would cover the entire half an acre with 3 inches of woodchip.
Soil life, I would spread/spray finish
compost + worm tea +
mushroom slurries over the entire half acre.
Mineral, rockdust, azomite, sea90, etc
Ground Cover, 90% coverage with dutch clover. 10% will consist of mint/thyme family, daikon radish, dill/carrot family, onion/chive family
Plants
I would plant on 15ft centers
Hazelnut
Currants/Gooseberry/Jostaberry
Blackberry/Raspberry
Quince/Pear/Crabapple/Apple (including the Asian species+Hybrids)
American-Asian Hybrid Persimmon
Pawpaw (Sunflower and Prolific)
Elderberry
Dwarf Mulberry
Blueberry
Juneberry (Regent+Prince Edward)
Seaberry
Goumi
Honeyberry
Jujube
Medlar
Arctic Kiwi (10ft vine)
Akebia (20ft vine)
Hardy Kiwi (100ft vine)
Grape (100ft vine)
Plum/Cherry/Apricot/Peach/Nectarine/Almond
Flying
Dragon Bitter Orange (because why not)
Vegetable+Herb Garden.
Have one near your house maybe even turn it into a 3-season hoop-house or 4-season
greenhouse. Might need some protection from chickens/etc.
Mushroom
Oyster Mushroom on strawbale
Wine Cap Mushroom on woodchip
The above doesn't need much prep or maintenance, but if you want something more involved then logs+drill+cap+watering also can be done for other species
Animals
2 Warre Beehive with just a April visit to split-recover and harvest.
Poultry, it sounds like you already have a good system already. The woodchip will have a bust of soil life that they will love.
Offsite 2 acre Pasture
The usual, swale+carbon+worm tea+mushroom slurry+mineral
Then daily rotational grazing (30 or more sections)
Pasture Mix
You might have to seed the pasture more often to keep it balanced.
Figure out a good species mix and percentage mix for your land. I like
40% Grasses
40% Legumes
10%
Medicinal (mint/thyme family, chive/onion family, dill/carrot family, etc)
10% Aerators/Miners (daikon radish, comfrey family, sunflower/dandelion family)
Barn
Your current manure production area (barn) has a wonderful purpose, keep on using it.
Goats Pen
If your future goat pen cannot keep in a dog it 700% cannot keep in a GOAT.
My family had a pig pen made out of
concrete, super strong and they never got away or knocked it down. but it could never contain a dog much less a goat. They climb, the jump, the move stuff to make a ladder, they are super smart.
Overall I wouldn't move the goat until another 3 years after you have done your other improvements.
