I live in Egypt and have chickens, ducks and goslings. Over the past week they have been dying daily. Their wings droop first, then they cannot stand and they end up having convulsions. This has effected the geese and ducklings mainly but we have had one chicken death in a similar way. One we have noticed is that goslings beaks and feet go very red and dark. We thought maybe it was because they were too hot, so we put them in the back garden with the water. But then one of our 2 month old chickens died in a similar way. Her feet too were deep red and she died over a few days. I have been keeping tabs on one forum about the convulsions in the goslings but this red beak/red legs thing seems weird. The chicken can get out of the sun but maybe it is a symptom of over-heating? Any ideas?
