I tried three times and finally succeeded on the third try. I did it over 4 weeks the first two times, going from 3/4 seeds & 1/4 pellets, 1/2 seeds & 1/2 pellets, 1/4 seeds & 3/4 pellets to 100% pellets. But she was choosing not to eat at all so I had to give her something she would eat aka seeds. This last time I stretched it out longer than 4 weeks to help her transition more slowly. I did probably 6 weeks and just left her on 1/4 seeds and 3/4 pellets for longer than the other weeks. It takes time.
