Greetings Mar,
If her crop is emptying by morning, this is good, she
doesn't have sour crop. Sounds like a slow moving crop, which may be due to another problem, maybe internal infection? You can continue your treatment today. Sometimes it takes many days for good results. I have not used Miconazole suppositories, so I cannot attest to the effectiveness.
In order to better understand what is going on with her digestive system,
can you please upload a photo of her poops. What do they look like?
What is her behavior like? Is she sitting fluffed up, lethargic, eyes closing/sleepy?
Offer her some cooked meat protein, diced fruit, diced black or red grapes, fresh chopped greens,
cooked grains like: brown rice, wheat berries, oat groats, pearl barley, also some toast with butter is good. Always offer her moist feed daily.
She should have soft foods while healing. This diet is good for chickens if that have crop problems. If she doesn't have enough diversity in the diet, her appetite will not be stimulated, especially if she is in captivity, away from the flock.
And, if she doesn't eat enough, her digestion will suffer, she'll become weak.
If you have probiotics, give her some. Also, some poultry vitamins. Follow the product instructions.
Clean fresh water daily. I like to add some echinacea tea or aloe vera, to boost the immune system.
God Bless and peace to you.
