I'm at my wit's end now with what to do about Sybil. In the past 8 weeks she and the other two chickens have had 3 courses of Baycox, 2 courses of Tylan, and been wormed with Flubenvet. I have sprayed her vent region with Frontline and, this week, because of no signs of recovery, she has had 2 injections of Tylan as recommended by the vet, who said she thought she could be in a downward spiral of respiratory and gut infections due to being run down. However she is still quite lethargic, and tail down. Over the past 4 days I have had her indoors as it has been so cold and she was just sitting huddled up in the corner of the coop. She seemed to get perkier after the first Tylan injection, but then went a bit droopy again (the second one was given by a locum vet who stabbed her twice before she got the needle in so hopefully it went in the right place. Sybil was NOT happy). She is in a box indoors so I am putting her out with the other 2 each day to get her legs exercised and make sure they remember each other. She does have to go through a bit of a pecking order ordeal each time, poor thing, but I find that if I distract them with food it's not so bad. Sybil does peck around a bit at the food and has a little groom, but mainly she sits there huddled up. She does walk slowly and sometimes stumbles but this could be due to her legs not being used to it. Inside she seems not 100%, but a bit better - she peeps a bit (used to be a real squawker), eats ok and is quite curious, but I worry she's not getting enough exercise. Her breath can be a bit raspy sometimes but the vet said respiratory illnesses can scar the airways and cause this. At least she seems to have stopped sneezing. Her poos are small and a bit wet but no wonder with all the medicine she has had. I have some Beryl's Friendly Bacteria on order (never used it before - any tips?). So basically she seems almost too well to keep in (she doesn't seem to be about to die), but not well enough to put out, especially with this damp and the below freezing weather we are due at night this week. I don't feel I can give her any more medicine, poor little thing. She is supposed to be 3 and a half years old but I'm not sure. I'm pretty certain her behaviour isn't just because of the season - she is normally the alpha female and the other two seem to be fighting fit - in fact Myrtle woke me up this morning complaining very loudly that I hadn't brought their warm mash out yet! I feel that all I can do is keep Sybil inside until she completely recovers but it seems to be taking a very long time. Maybe she has heard about Bottom and wants to be a house chicken too?! Anyway - as usual, any advice would be very much appreciated - thanks.
