A safe Stardew Valley Slime Hutch layout keeps the slimes away from you and their Slime Balls where you can collect them. I have been pretty harsh on this building in my videos, but if you want a slime collection, at least make it easy to maintain. The useful trick is combining barriers, water and flooring.
This focused guide expands the relevant section of my original Stardew Valley YouTube video, with updated mechanics for version 1.6. Jump to the part you need below.

Know what the Slime Hutch costs
Robin charges 10,000g, 500 Stone, 10 Refined Quartz and 1 Iridium Bar. The current building uses a 7-by-4 footprint outside and holds up to 20 slimes. Older footage may show the larger pre-1.6 exterior.
This is a hobby or a specialist production setup, not a building every beginner must rush. If your barn still has no feeding plan and your crops still need hand-watering, there are probably more useful upgrades to finish first.

Plan the Stardew Valley Slime Hutch layout before hatching
Divide the interior into a slime enclosure and a player collection area. Put barriers between them and keep the entrance connected to the safe side. Leave a way to service the Incubator without opening a path for the whole population.
You can use fences or other suitable blockers, but ordinary fences decay. Inspect the barrier as part of the collection route. A wall that used to exist is not much help when twenty slimes decide to greet you at the door.
Keep all hatching points inside the enclosure. A beautiful barrier does nothing if the next batch of slimes is born on your side of it. Walk through the plan while the building is still empty and check the corners.

Use flooring to choose where Slime Balls can appear
Slime Balls do not spawn on crafted flooring. Cover the enclosure floor, then leave clear, unpaved spaces in the safe collection area. This encourages the products to appear where you can collect them without entering the pen.
Do not cover the entire interior with flooring and then wonder why nothing appears. You are deliberately preserving a spawn area. Keep machines, decorations and storage from gradually filling every usable tile on that side.
The exact shape can suit your taste. The important rules are that slimes stay enclosed, their area is floored, and a suitable clear collection area remains outside the enclosure.
Water all four troughs
The hutch has four water troughs. Fill them with a Watering Can or place sprinklers so every trough is in range. Slimes do not have to physically walk to the water, so the troughs do not need to be inside their enclosure.
Use the first morning as a check: inspect all four troughs, the barrier and the clear floor. Do this before adding the rest of your decoration. A water problem is much easier to spot in a simple room than in a fully furnished one.
Build the population and collect the products
You need at least five slimes before the hutch starts producing Slime Balls. Marlon supplies a starting egg after the building is purchased; use an Incubator to hatch eggs and build the population.
A Slime Egg-Press turns 100 Slime into an egg. It can make the standard colours but does not produce Tiger Slime Eggs. Decide whether you want eggs to sell, eggs to hatch or a collection of colours. Those are different reasons for keeping the building.
Slimes raised in the hutch do not give Combat XP or count toward Monster Eradication Goals. You cannot replace a trip to the mines with an easy farm-based kill farm.
Add the Slime Charmer Ring and a Wicked Statue
A Slime Charmer Ring prevents slime damage and their slowing debuff. It makes mistakes much less painful, although I would still keep the safe collection arrangement. A layout should not become unusable just because you swapped rings for another activity.
A Wicked Statue inside the building prevents the Witch event from recolouring the slimes. My older script calls the visitor the Wizard; it is the Witch. If the colours are the whole reason you keep slimes, this is a useful precaution.

If nothing is appearing, check these first
Count the slimes, fill the troughs and look for unpaved, unoccupied floor. Then check that the new slimes really hatched inside the room and that you allowed the game to advance overnight.
On mobile, loading a mid-day save can affect trough water, so checking and refilling near bedtime is a sensible troubleshooting step. Do not assume a decorative change is harmless if it covered the last clear spawn spaces.
My final rule is simple: build the functional room first. Once collecting takes a quick walk instead of a fight, add the decoration that makes you want to visit it.
