Best Vitamin C (Ascorbic Acid)-Rich Foods for Chickens

Ranked by vitamin c (ascorbic acid) content among foods safe for chickens in the Creature Feast catalog.

#1
Broccoli per 100g raw: 89mg Vitamin C Broccoli is the richest Vitamin C source among commonly fed chicken vegetables. While chickens synthesize their own Vitamin C in the kidneys, supplemental C becomes valuable during heat stress, illness, and the physical demands of peak egg production when endogenous synthesis may fall short.
#2
Kale per 100g raw: 120mg Vitamin C Kale delivers excellent Vitamin C that supports collagen synthesis and immune function. During heat waves when chickens pant heavily and their own C synthesis may not keep pace with demand, kale provides a dietary safety net.
#3
Peas per 100g: 40mg Vitamin C Peas provide moderate Vitamin C that enhances iron absorption and supports immune function in chickens. During periods of disease challenge or environmental stress, the extra C from vegetable treats helps bolster the hen's antioxidant defenses.
