Hello, I need some help. I have been slowly losing pigeons over past few months, but lately it has been worse. I had wormed prior with Safeguard liquid and moved them to pens that use to house my ornamental pheasants(they moved to bigger pen).No change so i dosed with SG liquid added to water and mixed in feed for 5 days, as Im in Florida and parasites can be an issue. When that didn't seem to be helping i floated liquid Ivomec in drinking water for 2 days. no change. I noticed recently with loss of weight, a few days before death they will get liquid in their mouth and green stains around vent. I thought perhaps fungal so dosed with 2 days Metrotrondizole in water. Anyone have a clue what this is.
