Thanks. I have ducks, chickens (layers and meat birds), quail, microgreens, goats, young fruit orchard, and now turkey poults and goslings. There are customers for the eggs and goat milk and microgreens. There is a 1200 sw ft barn on 5 acres. 100 ft from the barn is a 1/3 acre pond and 500 ft from the barn is a fenced in dog run. The dogs and goats will walk there fine.
The main issue with the goats is that they persistently destroy their equipment. They smashed all their water buckets, hay feeders, and stall walls. Which is why it's so chaotic, wasteful unsafe, and time consuming with them. They also get sick and injured a lot so I am spending a lot of time and money with veterinary care.
The ducks and microgreens are the most profitable and easiest activities. However the ducks are indoors now due to predators and neighbors complaining about them roaming.
Quail are super easy and reasonably profitable once I got them all organized in a hutch.
The chickens are the least profitable simply because their eggs are a commodity, (I sell them for $4 but I'd really need $8/doz to cover time and expenses) and require moderate work.
For the goats; most animals if they get sick a lot then there's something wrong with the nutrition. Try to see if they still get sick if you put more diversity in the feed. I ran into this with ducks where they'd stop laying, or their ducklings would die immediately after being born. The problem went away when I added more nutrition to the feed. I also found a way of doing it without increasing costs. I'm not a goat expert, but when you say they get sick often that's what came to mind is to see if you can make them less sick. To find out what to do with this, I did experiments with feed ratios, that were more diverse. Hungry animals want to roam more also; though that idea has to be twisted a bit with goats, that are programmed to roam.
Does the water from the animals come from the house or from the pond? You might could see if you can close the distance to where they get water from, closer to where you do your feeding station...to save time?
Are your microgreens stacked, so the trays can be fed once from the top with it trickling down to what's under automatically? (I think you meant fodder sprout feed right?) When I did fodder sprouts I didn't have them stacked and that's what wasted a lot of time. I learned what I did wrong.

For the orchard you can cut your time if you focus on larger fruit, instead of the small stuff like cherries. Cherries are popular but when we process and pick cherries they take seriously like 3 or 4 times the time that it takes us to process apples, or peaches. And its all because they are so darn small that you spend forever pitting and picking them. (This will save you time, but depends on your sales market... can you sell other things...?) But a good added benefit of looking at this part is that many fruit trees like cherries are actually rated more poorly for some climates than others. Like in my state (Utah), plums are rated more hardy than cherries. So are pears, apricots, and apples... its also more gas mileage on maintenance and avoiding problems to just not do cherries here because the cherry trees in our yard take more time than all of the other fruit trees combined. We spend almost ZERO time maintaining the plum trees. And very little time on apple trees. But cherry trees, every year there's problems with them that take up our time. However, this could be different for your state. The ranking of maintenance time on fruit trees will vary on climate. But generally cherry trees are much higher maintenance still in other states. Larger fruit can process faster since you get more fruit in 1 go.
You could spend less on fertilizer for your crops and orchards if you set up some composting areas for the animal... manure.
The year I kept my ducks under the apple trees in our yard we also didn't have to spray for bugs that year also. (But my climate is unique... this might need experimentation for your area.) That saved time and headache. And spraying the orchard is ... well a lot of older farmers end up with bad health conditions from that. I hope you can avoid that.

Actually when I got to the end of writing this I realized, it might be that your goats are getting injured and sick from being in too small of space. They want to get out so they mess stuff up. Being too crowded can also get them sick. Its well known in the sheep industry that if you don't have good air in your barn that your sheep WILL get sick more than if there's good air circulation; particularly in winter when its also cold. (Although this is complicated if you've got more than 1 kind of animal in the same barn. Different animals have different body and blood temperatures and this weighs out cold resistance in winter).

People also get more allergic reactions to chickens, and chickens get sick more often now because all the bio and healthcare research including growing bacteria and viruses is done on those pitri dishes... and guess what, the stuff in those pitri dishes is chicken egg product. So that's why things are spilling over into other areas now with trouble with chickens. ... I won't tell you not to do chickens though because people are programmed to do chicken eggs. Most people wouldn't even think about doing duck eggs, though I think duck eggs are healthier. People with chicken egg allergies usually don't get sick to duck eggs too.
Well hope that helps. But some of these ideas you might have to weight out in marketing, selling.
