Posted by Chickens can safely eat Brussels sprouts—raw, cooked, whole, chopped, stalks, and even leaves! They’re packed with essential nutrients like Vitamin C, K, A, and fiber, which support immunity, digestion, and egg health. However, too many sprouts can introduce goitrogens, compounds that may affect thyroid function. Also, Brussels sprouts should be served plain, chopped, and in moderation. Curious about other veggies like broccoli, asparagus, or carrots? We’ll explore that, too!

Potential Risks of Feeding Chickens Brussels Sprouts
While healthy in small doses, overfeeding Brussels sprouts can cause issues:
-
Goitrogens: Naturally occurring in cruciferous vegetables, these can affect thyroid function and potentially lead to avian goiter (especially if your birds are already eating soy-based feeds).

Gas and Bloating: Excess fiber may cause gastrointestinal discomfort.
-
Imbalanced Nutrition: Too many treats can dilute their balanced diet from formulated feeds.
Note: Not FDA-approved as a regulated poultry feed. Always consult a vet if unsure.
