Update: Today I rang another vet who suggested it could be a bacterial infection, My original vet finally rang me after I left message after message, and said that the autopsy on the previously deceased chook showed she died of pancreatic cancer, and she also may possibly have had a bacterial infection in her peritoneum. Of course, they didnt test for that. !!
Anyway, he suggested antibiotics which I picked up today, along with Imovec? which is an anti worm anti parasite application that you can actually put behind the chooks head and is effective against a wider variety of pests that the Avi verm which I had previously been using.
I cleaned out her crop this morning, but all that came up was the porridge I had given her last night, and unfortunately she seems to have gone down hill a bit after that.
The alternative vet thought it may be tapeworm or something called selfengitis?
I read on the internet that you can clear their crop by giving them a small dose 0.1 of a ml of Parafin oil morning and night, so I have pulled out all the stops today, she has had parafin oil, a small amount of yoghurt, a small amount of Garlic water, lice and worm treatment along with antibiotics. I am also going to Lime out the coop and re disinfect it, although I have done that twice already
I dont know what else to do!! Shes not looking that good this evening, I hope she makes it thru the night. She was an ex battery hen and is the most loving and intelligent girl. I will be gutted if she doesnt make it
Fingers crossed
