✓ Fresh, plain lettuce: SafeSuitable as a limited green treat.
Why this answer
Extension guidance permits greens as supplements and warns that excessive scraps dilute a balanced ration.
Serving guidance
Offer a few clean leaves for the flock to share and remove soiled leftovers. Keep all treats supplemental to a complete, life-stage-appropriate ration.
Discard slimy, wilted, or moldy leaves and wash the rest.
Tear large leaves or secure a clean portion for supervised pecking.
Serve plain, without dressing, salt, oil, or seasoning.
Keep the baseline
Complete, life-stage-appropriate feed should remain the nutritional base. Do not offer spoiled, moldy, salty, or seasoned leftovers.

Aggregate search statistics
When you submit a search, the browser drops queries that look like an email address, URL, or phone number, as well as queries containing control characters. Never enter personal information in the food search.
