Backyard chicken care

Know the signs. Protect your flock.

A practical, easy-to-scan resource for recognizing common chicken-health warning signs, taking safe first steps, and keeping essential care supplies ready.

Check warning signs

Observe daily

Watch appetite, energy, breathing, droppings, eyes, comb color, movement, and egg laying.

Separate safely

Use a clean isolation area when a bird seems sick, while maintaining food, water, warmth, and low stress.

Act promptly

Rapid decline, breathing difficulty, neurological signs, or multiple affected birds warrant professional guidance.

Warning signs to take seriously

One sign alone may have several causes. Look for changes from your bird’s normal behavior, and note when they began, how many birds are affected, and whether symptoms are worsening.

Comb, wattles, and face changes

A pale, blue, dark, swollen, or otherwise unusual comb/wattle color can accompany circulation, temperature, injury, parasite, or illness issues.

Eye or nasal problems

Cloudy, watery, swollen, crusted, or pus-filled eyes; discharge; and matted eyelids deserve attention, especially with respiratory signs.

Breathing changes

Sneezing, coughing, wheezing, open-mouth breathing, rattling sounds, or nasal discharge may spread through a flock and should be monitored closely.

Low energy or abnormal posture

Closed eyes, isolation from the flock, drooping wings, tail down, weakness, reduced eating, or straining can signal illness or pain.

Crop or digestive concerns

A crop that is persistently hard, overly full, sour-smelling, or squishy in the morning, plus diarrhea or bloody droppings, calls for prompt assessment.

Skin, feet, and parasite clues

Excessive scratching, feather loss, scaly legs, sores, swelling, limping, or black scabs on the foot can indicate parasites, injury, or infection.

Four calm, practical first steps

1

Isolate

Move the bird away from the main flock if possible, using separate equipment and limiting unnecessary handling.

2

Support

Offer clean water, appropriate feed, shelter from weather, and a quiet, clean place to rest. Avoid force-feeding unless directed by a professional.

3

Document

Record symptoms, droppings, feed and water intake, recent changes, new birds, injuries, and how many chickens are affected.

4

Get help

Contact a poultry veterinarian, diagnostic laboratory, local extension office, or animal-health authority when signs are serious or spreading.

Seek urgent professional help when needed

Contact a veterinarian or appropriate local animal-health resource promptly if a chicken has severe breathing difficulty, cannot stand, has seizures or other neurological signs, has a serious injury or prolapse, dies unexpectedly, or if several birds become ill or die in a short period.

  • Do not move sick birds between properties or share equipment with other flocks.
  • Wash hands and change footwear or clothing after tending an isolation area.
  • For sudden or unusual flock illness, follow your local reporting guidance.
