Two months ago my two red Hampshire bantams became ill, loose droppings, pale comb etc, I advised the vets (there is no vets within 50 miles that know about chickens) that it resembled coccidiosis and asked for them to examine some poo. They agreed and did tests, indeed there was a high diagnosis of this but as the vet rightly stated there may be something else other than this that they do not know is causing it. They gave them two days worth of antibiotics and told us that if it continued after this there was nothing they could do but wait for the chickens to die and do a necropsy. After a month and a half one of the chickens has improved, however the other is still poorly and is now providing a very dark runny poo. The wet weather (edge of a hurricane) doesn't help. Is there anything anyone can think of I can try to save poor Mollie-she's been fighting this for near two months! She's such a fighter but I think she's losing the war.
