Is she pooping?I checked her crop this morning and while it isn’t huge, I can feel a smallish golf ball sized lump, which is squishy. She doesn’t seem to be in distress when I poke it. Yesterday during the day it felt much larger and harder. I compared this morning to another chicken’s crop, which was completely flat. So I think maybe a partial impaction, possibly? No noticeable odor coming from her beak. I’m reading all kinds of things online, from completely isolating her and cutting off food and water for 12 hours, to olive oil and yogurt and forced regurgitation.
Also, regarding the heat stroke theory, she is an Ameraucauna and does not seem to tolerate the heat well and is drinking a LOT.I was blaming it on heat until I saw the liquid coming from her beak yesterday. That got me worried.
Here’s a photo of her this morning, panting, though it’s not hot yet.
I would start by reading the article below. Give her 1 teaspoon coconut oil twice a day and massage/manipulate the material that's in the crop. See how the crop is in the morning. If it's gone down or not much different, then I would repeat the coconut oil. If the lump is still there again the next day, then I would give the stool softener. IF the crop changes from the lump to being boggy, re-read the article and let us know.
Generally I leave mine with the flock unless I can't resolve the crop issue over the course of several days. Separation is stressful on birds.
During this time make sure that grit is available free choice to the flock. I would cut out any treats that are harder to process (corn/scratch/seeds) and opt to give the whole flock (including her) a treat of scrambled eggs or similar.
Is she laying eggs at all?
The flock has shade?
If possible, provide cool water for them to drink a couple of times a day.
