Can chickens eat coffee grounds?
No – toxic. Chickens should never eat coffee grounds. Coffee grounds, energy drinks, tea bags and other caffeinated products are dangerous for chickens, says UF/IFAS Extension. Caffeine affects the nervous system and heart and can be fatal. RSPCA Australia lists caffeine among things chickens should never get.
Did your chicken eat some?
If your hen ate something toxic or seems unwell, call your vet – the RSPCA says to always contact a vet if you’re concerned. Keep a sample of the feed (Merck Veterinary Manual).
