I have some <5month old birds which are having rouble adjusting to a new home and lots of snow. Ive heard poultry spice is good for them in times of stress, like some sort of tonic that also helps them eat more? I looked at the ingredients, and other than the mystery mineral mix I have abundant amounts of the spices at home. Would it help if I added some to their feed? Ingredient(s): Minerals, Micronised Wheat, Powdered Ginger, Turmeric, Fenugreek and Aniseed.
