Can chickens eat slugs and Snails?
In moderation Yes, in small amounts
Chickens eat slugs naturally and they aren't toxic, but slugs and snails can carry poultry parasites.
Why
Merck says several slug and snail species are intermediate hosts for the chicken tapeworm Davainea proglottina (over 1,500 infective parasites recovered from one slug), and slugs and snails are among the transport hosts linked to heavy gapeworm infestations.
How to serve slugs and Snails
- Let birds forage naturally rather than collecting buckets of slugs
Be careful with
- Don't feed slugs collected from areas treated with slug bait/molluscicides (pesticide rule)
- Watch free-range flocks for signs of worms
The treat rules for every food
- 1Scraps are not nutritionally balanced. Letting them displace complete feed can cause nutritional disorders and lower egg production; hens that fill up on treats can run short of calcium and draw it from their bones, weakening shells.
- 2Never feed moldy, rotten or spoiled food. Molds can produce mycotoxins (e.g., aflatoxin on corn, peanuts, nuts, rice) that harm poultry, and University of Kentucky notes mycotoxins remain even if visible mold is removed. Rotting food can also be a source of Clostridium botulinum (botulism, 'limberneck'). Stale or wilted (not moldy) produce and bread are generally considered fine.
- 3Avoid very salty, sugary, fatty, fried or heavily processed human food (chips, fast food, candy, heavily salted leftovers). Merck notes salt above about 2% of the diet is usually considered dangerous for poultry, that birds under 21 days old are more susceptible, and that restricted water access makes salt problems worse.
- 4Provide insoluble grit (granite grit or small stones) whenever chickens eat whole grains, scratch, seeds or forage; birds that can reach the ground usually find their own. Oyster shell is a calcium source, not grit (it is too soft). Birds eating only a complete pelleted feed do not need grit.
