Any suggestions please. Have sick 10 week old cochin - been ill for a week and I have it in isolation - it is doing fairly solid poos but also losing clear liquid from vent - vent feathers are soaked in it. When it poos it makes a noise like a hyaena which I assume is a pain noise. Do not think it is coxxi as no sign of blood. The bird is a bit humped up and depressed and is still eating but not much. Have treated for 5 days with Coxoid and this has had no effect. Thinking about sending off a sample for analysis or trying with antibiotics. The most striking thing is the hyaena-like noise it makes when it poos or when the waterly liquid comes out of its vent. Any suggestions please. 2nd bird outside also showing symptons so need to act quickly.
