My pouter male, whom I've had two weeks, has been lethargic since this morning, with his neck drawn torards hs shoulders & his eyes looking sleepy & dull. Two days ago he had a play date with our serama cockerel (who's his best buddy), in a dog kennel on the deck and my daughter gave him finely chopped stems of some Chinese collards or kale. He ate quite a bit, as the Serama likes to eat these regularly, and his (pigeon's) poo has been neon green ever since. Today it is foamy. He did eat his breakfast of ground grower feed with added millet. Could this be something like coccidiosis? The deck was power washed two weeks ago. It's really clean. If he has something, what might it be? what could I treat him with? I use Amprolium for my chickens. The pigeon's adolescent mate didn't eat the stems, and she's fine. She didn't walk around with the Serama cockerel. The Serama cockerel has been raised with a mate separate from any other birds. His health is great.
