I have been giving my birds dandelion leaves and dandelion flowers throughout the year, and I heard they can eat marigold flowers. I want to get them some seed(I would be growing seeds and feeding the flower to the birds.), but I've seen that the pesticides in the soil get stored in the seed and can kill the bird. Does anyone buy flowers or seeds for their bird, and where to you get them? And can pesticides stay in the seeds and kill the bird? If they are safe I would be getting mckenzie or aerogarden seeds and growing them indoors in either an aerogarden or potting soil. Or I will find a site to buy seeds off of.
