I have dug up the planting area where the bulbs were for several years. I'm adding better soil.
These will be best planted in late November in zone 10. Here is an article that will help:
I live in Georgia and we have been having warm weather, now my daffodil bulbs are coming up what do I do it's going to be really cold next week.
Cover them with more soil and mulch if they are just an inch or two above ground. If they are further along, you can add more mulch and cover them with cloth or boxes when freezing weather hits. Here is more:

Can you start Daffodil bulbs in January? We live in Cumming, GA and I have the bulbs.
While January may be late for planting Daffodil bulbs in Cumming, GA, you can still try it if the bulbs are in good condition. Choose well-draining soil, plant bulbs 6 inches deep with 4-6 inches spacing, and water thoroughly. Keep the soil consistently moist and consider applying mulch for temperature regulation. Note that late planting might result in delayed or erratic blooming due to the lack of sufficient chilling hours for the bulbs. Monitor the bulbs closely and provide proper care for a chance of enjoying spring flowers.
This article will give you more information n the care of the flower:
Have a pot of daffodils. If I plant them in the garden now, will I have to dig up the bulbs and replant them in the fall?
Likely, it is disrupt their cycle to plant them now. These need to be planted from September to November, while they are dormant, to give them the proper chill hours. It will give them a chance to complete the rest of this cycle so that it has energy to store for flowering by the fall. You can leave them in ground after that. They prefer much colder, but tolerate our warmer temperatures in zone 7.

I have planted several varieties of daffodils over many years. Now most of them all look the same. Dark yellow center with cream petals. This was one variety I planted. But also all white and all yellow. They seem to be changing so they are all the same. Almost all are the bright yellow center with almost white petals. Is this possible? Are they cross pollinating?
Most likely the other varieties ae dying out and leaving the one variety, which is multiplying by bulb increases. To get more bulbs by seed, you would need to hand pollinate. The seed is too heavy to be carried by the wind, and insects do not pollinate them because there is no nectar to attract the insects.
They were allowed to die naturally before cutting.
They should be just fine. I would test the soil in the area. If it gets fertilized often, Then watch out for too much nitrogen in the soil. This will prevent uptake of phosphorus and potassium, which will keep it from blooming.
On the other hand. If you do not feed them often, then it could be that it is actually lacking in phosphorus and potassium. Feed with bloom formulas, or just something with high potassium and phosphorus. Otherwise, once you get them to bloom again, just use a fertilizer made for bulbs.
This article will offer a more detailed look at different ways to feed them:
