I don't fertilize at all Randy. It is really odd this year. I have a couple of hens that have this spring's chicks still attached and some of the chicks are blooming. I'll have to go take a picture.
I just went and took the pictures. Guess what, both of these are ones I bought this spring and were nursery grown (so probably fertilized). Non of them I have had for a year or more are doing it.
