“I have raised pet owls.
“They need roughage in the diet. If the writer is in Malaysia or another ASEAN country, the problem is easier to solve.
“If the writer is in Singapore, it can still be solved, but will cost more money.
“First things first. Is the bird in question an owl or an owlet? By which I mean is the bird currently smaller than about 12 cm (5 inches) and would its adult size be assumed to be less than 16 cm (6 to 7 inches) or is the bird larger than that?
“Insects and lizards make up a large proportion of the diet of the small owls.
“The larger owls eat birds and rodents.
“Now to the feeding. Let’s start with a larger owl. In the old days in Singapore, there were still many poultry farmers, and hatcheries that provided chicks for their business. Not all chicks hatch properly. For very nominal payments, the hatchery owners were more than happy to sell me their deformed chicks which farmers would reject. And in a large commercial hatchery, there are always at least a dozen deformed chicks every week.
“Simply cut them up, and feed them to the owls, feathers, bones, everything. This will provide the roughage that the owls need. And this will be the diet even after the owls reach adulthood. Sometimes, hatchery owners have bad sessions, and have loads of deformed chicks. In such a situation, those you don’t need today can be frozen for future use. But please ensure that they are properly thawed and served at room temperature to the owl.
“If you do not have a supply of deformed chicks, then there is something else that works, but only as an interim measure. If you have a pet cat or dog, you can comb it out, cut up the hair, and roll it together with chicken flesh before feeding this to the owl. I must admit that this is not an ideal solution, but it might stop your owl’s stomach troubles until something better comes along.
“But please make absolutely sure that there are no grooming conditioners, insecticides, or flea shampoos in the hair that you intend to feed to your owl.
“Now, if you have a little owlet, you feed it with some meat (with hair, skin and bones attached) but the bulk of the diet should comprise insects. Fortunately, crickets are now bred on a commercial basis, and most bird shops sell them.
“The crickets are usually not in good condition when you buy them from the shop. The pet shop owners don’t want them defecating and urinating to mess up their displays, so they have minimal food and drink before being sold. They are therefore malnourished and not very nutritious.
“For the long term, you need to feed your owlet with well-fed insects. I have found that a mixture of high quality chicken food and fish food fattens crickets very well. And for moisture, I give them orange slices. This also provides Vitamin C. Don’t worry, it is not expensive. Crickets are small, and even a hundred of them take a week to finish a single orange.
“My system for my songbirds is to buy crickets and fatten them for a week, then only feed them to the birds in the second week, while a new batch of crickets is being fattened.
“Songbirds have no problems with catching and killing their own crickets. For a baby owlet, you might have to kill the crickets. The way to do so is to put them in a bottle, and put the bottle in the freezer. But make sure that the crickets are thawed to room temperature before offering them to the owlet.
“I have to mention superworms and mealworms. These are the larvae of beetles, and are sold in pet shops for feeding birds. Some aviculturalists have reservations about using them as bird food, but I find that they are OK as long as you are very careful.
“First, like crickets, they are usually malnourished when they arrive in the shops, packed in oatmeal. You have to fatten them with chicken feed.
“Second, they are full of starch, and do not make for a good, balanced diet. They should never be the staple diet of your bird, but can only be served as side dishes.
“And third – absolutely the most important point. They can kill baby birds. Adult birds know how to make sure that the worms are truly dead before consuming them. Baby birds do not know this. The worms do not die immediately when swallowed, and can continue biting to damage the intestines of the baby birds.
“Make sure that mealworms and superworms are well and truly dead before you feed them to baby birds. You can kill them the same way you kill crickets, or you can simply cut the heads off with scissors.
“If you feed the owl or owlet with a diet that contains enough roughage, the stomach should stop running, and it will soon start to cast pellets. This is nothing to be alarmed about. It is absolutely natural for some types of birds to vomit out the undigestible parts of their meals a short while after eating. But it is these indigestible parts of the meal, which must be included in the diet, that allow the stomach to function properly.”

Attached is a photo of the owlet (above). Thank you all once again.”
