When I have a bird that is acting 'off' I isolate bird in a wire cage within the coop for a day or two....so I can closely monitor their intake of food and water, crop function(checking at night and in morning before providing more feed), and their poops. Feel their abdomen, from below vent to between legs, for squishy or hard swelling. Check for external parasites or any other abnormalities.
Best to put crate right in coop or run so bird is still 'with' the flock.
I like to use a
fold-able wire dog crate (24"L x 18"W x 21"H) with smaller mesh(1x2) on bottom of crate under tray.
Then you can put tray
underneath crate to better observe droppings without it being stepped in. If smaller mesh is carefully installed, tray can still be used inside crate.
Is it hot where you are?
Get some electrolytes into her.
I give a dose of
Sav-a-Chick electrolytes/vitamins about once a week during heat waves.
It
really seems to help....started this after they saved a heat stroked hen once.
Can mix up a smaller amount, just wrap the packet tight and store in a dry cool place.
Always have plain water available too.
I use a Qtip soaked in Sav-a-Chik solution held against the side of her beak, had to rub under her beak and the front of her neck to get her to swallow at first.
Or you could syringe, very careful , like this:
