The pet shop we go to offers free 'grooming'/wing clipping so every time we bring her in they just do it for us. We have 2 pedi perches, a mineral wheel, and cuttlebones for her too! and I felt like it was safer to keep her wings clipped because our house has a lot of windows and fans (my family are not bird people so they don't really do things like turn off the fan when the bird is out etc.) and the doves we had always used to get into trouble when their wings weren't clipped.Lots of great responses Sprouts are a fantastic option and there´s lots of tips on Mizzelys article.
Try sprinkling some millet on top of veggies, or mixing in some quinoa. Some birds like to pick at bigger pieces of veg, others like chopped up bite size pieces.
Bird breads and mashes are great to try.
Remember to be persistent, patient, offer lots of variety and accept any waste while you are introducing new foods.
Also, a 3 month old bird doesn´t need their nails trimmed. Buy a good quality pedi perch and save your money (I own hagen and some of my birds go over a year with no nail trims, again, all birds are different).
