Fluid pouring from hen's beak. Help please.

Oh dear,  looks like the second of my ex bats is poorly.  We've had them 18 months - they were 18 months old.

Little Henna is sat looking terrible.  tail down, almost gasping.  Very pooy bottom and I've just picked her up to inspect, and a load of fluid has just poured from her beak.  I've placed her quietly back on the grass away from the the others with water and some food, but no interest.

Please can anyone offer any advice asap.

Thanks as ever.

Seems that way.  Pooy bum cleaned and dried, crop - emptied.  Been advised to feed some live yoghurt to combat the nasty bacteria.  See how she is in the morning.  She's sleeping in our house in the warmth tonight.

Hope Henna is perking up. I give my four hens 2 dessertspoons of live yoghurt between them every evening.  If I've got freshly cooked veg available they have a spoonful of that chopped in, or sometimes a spoonful of plain cornflakes. They make a terrible mess and get it everywhere but they really love it.
