Yes, that is a pin feather and it is perfectly normal.
Budgies generally have a first light molt at around 3 - 4 months old and another at 6 -7 months old.
When a budgie reaches at 1 year old their molts adjust to the Seasons., After the adjustment the budgie will have its big molts in the Spring and Fall. Budgies may also have lighter molts throughout the year; triggered by stress, change in diet or change in environment.
You can supplement your budgie’s diet with egg food during a molt.
This helps your budgies replenish the energy lost during the time they lose and grow in the new feathers.
Additionally, egg food promotes good and healthy feather growth.
It is possible to buy ready-made egg food at any specialized pet store but just as easy to make your own by hard boiling an egg and mashing it up.
If you wish you can mix it with a bit of cooked quinoa and flax seed.
You can also finely chop some veggies and add it to the egg food mix.
If your give your budgie cooked quinoa, be sure you rinse it well several times before cooking.
Budgies get itchy during their molt, so they'll preen and scratch more often. Additionally, they may be sleepier and quieter as molting takes a lot of energy, and their poop could be a little runnier. To make them more comfortable, you can offer them baths either in a shallow dish of water (or Lix-It bath) or by hanging wet greens (romaine lettuce or kale works best) in their cage so they can nibble on it and rub against them.
