I added 1-2, 240mg B2 capsules to wet mash, & fed that to the worst one, & popped a pill in her beak as many times in a day as I could. Which was about 3-4 times a day, along with Riboflavin enriched wet mash. Usually not at the same time.

Earlier this year I had 2, 6 month old Silkies come down with Vitamin B2 deficiency. Took about a month too cure for the worst one. I fixed the problem with B2 capsules.
Add poultry Cell to their water daily as a nutrient boost, or as instructed on the bottle. Every day isn't necessary.
An All Flock, or Flock Raiser feed. It's formulated for everybody. I supplement calcium in the form of oyster shells in a separate feeder, or container.
Layer feed isn't a great feed for none high Production breeds. Nor is it good for roosters/cockerels. It's formulated primarily for high Production hybrids/breeds such as Golden Comets, Isa Brown, other Red Sex-link varieties, & Leghorns, just to list a few examples.
Too much of a good thing can lead to problems in the future. Treats should only be given maybe once a week, once every couple weeks, or once a month as a healthy frequency.
