I read the post on feeding, and have seen info here and there but I have questions about my two pigeons living on my roof. I have been putting out a "wild bird seed" mix containing milo, white proso millet, black oil sunflower seed, calcium carbonate. I also put out fresh water daily. I never see them do anything other than roost under the eaves all day, fly a few laps around the house in the morning and late afternoon, and come down to the food I leave by the spa. So if they are sourcing any other kind of food, I don't know when or where. There is a patch of grass just below them, but I have never seen them on it or near it. Should I be adding some kind of grit, as I have seen mentioned, and if so, what do you recommend? Also, do they need to have greens added? I buy little containers of wheat grass, is that something they can eat or do they need to have something chopped up fine? I saw someone mentioned broccoli in a mix but that seemed to be a wet mix (meal) so might have been powdered - can they eat little pieces of broccoli? I don't want to confuse them or make them sick. I had thawed out some frozen blueberries with the idea of putting those out, but then thought I had better check first, in case it upsets their system, or maybe it is bad to have berries out of season. Or worse, they love them so much they won't eat anything else and if I am not always here, they won't find blueberries anywhere on their own. We do have to think about how what we do affects their impressions, right? I would like to think they can find some kind of food on their own if something happened that we can't put food out for them. I don't know how to help them without making them dependent. I don't want them to go into someone else's yard looking for food as they would not be welcome. But I guess in the short term, I want to make sure they are getting all the nutrients they need. It seems people are feeding their pigeons a lot more than just "wild bird seed" mix. Any advice is appreciated, especially about grit and greens, thank you.
