The appropriate paint to use on a toilet bowl is an appliance epoxy spray paint. However, even that won't stick to the toilet bowl unless it is abraded and primed first. Drain the water from the toilet bowl and let it dry. Once it's dry, sand it until the surface feels gritty. Next, prime it with an acrylic latex spray primer. This prevents the epoxy paint from eventually flaking. Pain the toilet bowl however you'd like.
It is actually best to give them natural shells. While painted shells may seem fun and attractive to you, even paint that is labeled "non toxic" has not been tested for safety with hermit crabs. Hermit crabs tend to nibble on most everything in their environment. Imagine if you ate a whole bowl full of paint chips. Whether it was "non toxic" or not, it would probably still make you sick. Because hermit crabs eat such small amounts, a few nibbles of a paint chip would be like eating a bowl of paint chips for you. Nail polish is definitely unsafe for them, and acrylic paint isn't good either. If you own a hermit crab with a painted shell, offer him several different natural shells (which are much more beautiful) so he can move out. Once he does (and he was forced into that painted shell to begin with, they don't paint shells with crabs in them), remove the shell and don't let him have it back. You will likely find that the paint has already been chipping off.
A painted steel bowl is oven safe, as long as the paint is enamel.
Look in your local art store for the pen,and in Home Depot for the paint. if they don't have your exact colour they will tint it.
Pastel paints are an oily medium that looks like a crayon. One would start with a paper meant for pastel paint. One should start with dark colors first, blending and lightening the colors as they go along. With pastels, one can draw water landscapes, sunsets, fields of flowers, still life such as a bowl of fruit, and people.
I suggest to you that any paint would harm an animal or a chicken. Paint contains chemicals and that would get into the water. Go get a plastic bowl that you can clean and won't rust.
If it leaks, use a aquarium sealer.
Decorating outdoors doesn’t have to be costly or standard. Many items can be made into interesting and useful outdoor decor pieces with a few simple tricks and placement ideas. Use an old toilet for a planter. Once considered an object of refuse, toilets are made of durable porcelain and if treated properly, can prove to be an attractive planter piece suitable for placement outdoors. First, remove the tank and seat. Scrub the entire toilet bowl with bleach and let sit to remove stains or rust spots. Sand the porcelain surface only on the outside and along the rim using coarse, 50 or 40 grit, sandpaper. Wipe with tack cloth to remove dust. Paint the bowl using automotive primer and paint in any color you choose and allow to dry. Apply more coats if needed. After the bowl has dried, bury the base, if desired. If the bowl will be seated on a solid surface such as a patio, porch or walk way, fill the bolt holes with some wood putty or caulk prior to painting. Place rocks at the bottom of the bowl for drainage, then apply dirt and plants. It’s best to find plants that will spread and drape over the sides of the bowl to compliment its shape. If you’d prefer to keep the tank attached, remove the cover and paint it the same color as the bowl. Use spreading plants with flowers in an alternating color to contrast the flowers in the bowl. Old toilet bowls can also be re-purposed and made into an outdoor decor table base. Fill bolt holes with caulk or putty and let dry prior to painting. As instructed above, clean, prime and paint the bowl in any color fitting your personal taste. For more interest, use a spray paint with a stone or sand additive to give depth and character to the piece. After the paint has fully dried, fill the bowl to its edge with plastic, silk or dried flowers or an array of colorful and decorative stones. Apply rubber or felt adhesive pads along the rim to cushion a table top. For outdoor use, a tempered glass top is recommended.

You could paint a bunch of pinecones and put them in a bowl as a decoration. Such as near Christmas, you could paint some pinecones silver and gold or red and green.
To make face paint out of tempera paint, you mix flour and water in a small pain on the stove until it is of the right consistency. After you remove the mixture from the heat, separate it into several bowls and add tempera paint to each bowl until you get the shade that you want.
