It will re-coagulate and cling to whatever parrot food is in the food dish, helping to bring oil to your Sennie’s integumentary system.
From Wikipedia we learn
The integumentary system comprises the skin and its appendages acting to protect the body from various kinds of damage, such as loss of water or abrasion from outside.
The integumentary system includes hair, scales, feathers, hooves, and nails.
It has a variety of additional functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature.
In most land vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis.
Now let’s circle back and talk about what parrot food we should use as a daily diet for your Senegal.
It’s a lot to ask of a bird to make a transition directly to bird food pellets after 10 years of seeds.
Pellets are also not an end all to end all.
Thus another reason we recommend blends like Hagen Tropimix and Higgins Safflower Gold is that both have a well-rounded mixture of fruits and nuts and seeds.
The two bird food blends include their branded pellets as well.
Any and all bird food blends in the Higgins bird and parrot food lines, contain InTune pellets, so the bird is starting out with a well rounded avian nutrition foundation.
For the record, our seven birds (we have six budgies) eat what we get in broken bags, tubs and boxes.
All the birds are good eaters, we don’t overly pamper or cater to their needs.
Throughout the day the birds will get everything from almonds (for Peaches) both shelled and unshelled.
Nutriberries, Avi-Cakes, slices of cucumbers, lettuce in their dishes, over their food and in the budgies bath.
When we have dinner, Peaches joins at the table and usually gets what we are eating.
She’s a lover of protein and likes chicken, pork and beef.
She likes her veggies but only when they’re warm.
The lettuce better not have any dressing or other slimy condiments either.
In conclusion: just spend time with your bird, consider perhaps clicker training which will help engage him which may take his mind off plucking and preening.
The healing process could take a year, it may take six months or even two years.
Have no expectations, just enjoy your bird.
