Can Chickens Eat Milk?

In moderationSparingly — they can't really digest it

Milk isn't toxic to chickens, but they digest lactose poorly — small amounts occasionally, or skip it without guilt.

The why

Chickens don't produce much lactase, so milk in quantity ferments in the gut and exits as diarrhea. Small splashes (or better, fermented dairy like clabber, kefir, or yogurt) are the traditional farm use.

How to feed it

Moisten a mash with a splash of milk occasionally, or offer soured/fermented milk products instead.

Worth knowing

Watch droppings and scale back at the first sign of looseness; never leave milk-soaked feed to sour in summer heat.

The 90/10 rule: whatever the treat, a laying flock's diet should stay about 90% balanced feed. Treats — even the healthy ones — are the garnish, not the meal. Wondering what your flock really costs to feed? Try our free egg cost calculator.
