Hello. I hope that someone may be able to advise me about a problem with one of my three backyard birds. Colombian Blacktail, around 20 months old, with all the usual vaccines. Came back into lay after the Winter for just a month, then stopped around 10 weeks ago. Some soiling near cloaca, which otherwise looks healthy. Comb is correct colour, crop not obviously impacted. Feathers not fluffed up. Bird appears very depressed, will come out and forage a little but has lost condition over time. When picked up tends to regurgitate fluid. I have just put her on Flubenvet rations, though there is no obvious sign of worm infestation. Bedding recently changed from wood shavings to hay. Any suggestions would be very welcome.
