Reasons for Sour Crop and Slow Crop

[Lavender6]

The best thing that has worked for me with birds who have slow working crops is to feed small meals several times a day. No yogurt, low fiber (no grass or hay in run), and plenty of water. These birds don't need a complicated diet. Mine have done well on layer pellets in limited amounts with occasional apple or cantaloupe for treats. If I think I need to add probiotics I use benebac for birds and add a sprinkle exact hand bird feeding formula to the diet. Chronic cases may need a crop flush and be evaluated for viral or bacterial issues. Do not let a bird with a history of sour crop to engorge on any type of food. Keep the diet simple and in limited amount. I have two hens who have issue with their crop and as long as I keep the diet simple they do great.

That might be my problem. I put their food down and they free eat. I let them eat their crumble as much as they want. Have you ever heard of a molasses flush? Is it recommended and how is it done?

Flush amounts.

If the hen won't drink it on her own, then syringe or tube the flush into her. You will need to determine if her crop will hold all the liquid and take care she doesn't aspirate.
