I am looking to make my own basic seed mixes for a GCC and a tiel.

My husband has celiac disease and we have a little one on the way that may as well. We are taking our ENTIRE household gluten free (no wheat, barley, rye or their derivatives) including the pets to avoid cross contamination. Between the dog and the birds they are tracking gluten all over the furniture and us! The dog food I have figured out but all the standard seed mixes have wheat or barley in one form or another. Cracked, crushed, rolled, or whole it is still poison to this family.

Does anyone have a basic recipe for what seeds should be in the mixes for a GCC and a tiel? I am prepared to do all the scooping, bulk buying, and mixing necessary (as well as our normal mix of fresh foods) but I want to make sure all the bases are covered. What about ratios for millet, sunflower, dried fruits, nuts, etc?

Has anyone encountered this problem before? Have you found any pre-made options?

Thanks much!
