Overview
If your hen has a distended abdomen and is off her food, it’s sensible to treat it as a real concern. The cause may be something relatively simple, but it can also be linked to egg binding, internal laying, infection, fluid build-up or another abdominal problem, so it’s worth checking her closely and getting advice if she doesn’t improve quickly.
Things To Check
1. See whether she is still passing droppings, and whether they look normal in size, colour and consistency.
2. Check if she is straining, standing hunched, walking awkwardly or repeatedly sitting down as if uncomfortable.
3. Look and feel gently for any obvious swelling, firmness, heat or tenderness around the lower abdomen and vent area.
4. Notice whether her vent looks dirty, stretched or soiled, which can happen if she is struggling to pass an egg or droppings normally.
5. Watch for changes in her posture and breathing, such as tail bobbing, puffing up, weakness or reluctance to move.
6. Check whether she is drinking at all, as a bird that’s not eating or drinking properly can go downhill quite quickly.
7. Think about any recent changes in laying, moulting, flock stress, diet or access to grit and water.
Common Causes
Egg binding is one possible cause, especially if she is laying, straining or looking uncomfortable.
Other common possibilities include constipation, reduced gut movement, internal laying, egg yolk peritonitis, fluid build-up, or a crop or digestive issue that’s making her feel generally unwell.
Less commonly, a mass, injury or another abdominal problem may be involved. You can’t confirm the cause at home just by looking, so the pattern of signs matters.
What To Do
Keep her somewhere quiet, warm and easy to observe. Make sure she has fresh water close by and offer her normal feed, but don’t force food if she’s unwilling to eat.
Check her a few times over the next few hours for droppings, posture, breathing and whether the swelling seems to be changing. Keep handling calm and brief, because stress can make things harder for her.
If she seems dull, the abdomen is very tense, she stops passing droppings, or she becomes weaker, get veterinary advice promptly. A hen with abdominal swelling and reduced appetite can deteriorate quickly.
Products That May Help
Keeping hen housing, feeders, drinkers and handling areas clean can help support good day-to-day flock management while you monitor a bird that isn’t right.
