Help needed, yet more problems---advice on 3 unwell chickens

Hi, more help needed (I think I am about to give up)   I bought some day old legbars and exch leghorns about 12 weeks ago and then 2 Cotswold legbars which I kept isolated for 3 weeks.  Two weeks ago I lost one of the leghorns to an impacted crop. Last week I lost one of the Cotswold legbars, I found it dead in the coop, no obvious signs and been eating drinking etc ok. On Saturday one of the Cream legbars was ill, runny pooh, crestfallen etc. I isolated her and gave her coxoid solution. I jetwashed the coop with poultry shield and then covered it with a DT slurry.

 Today her pooh is back to normal but and she is eating and drinking but she is sneezing a bit and her eyes are watery and either side of her nostrils are swollen. Then I found the leghorn crouched up and lethargic, and felt cold, so I dosed her with coxoid and put her in with the legbar in an isolation cage. She appears to be eating ok  but I haven't seem her poohs yet.


Thirdly I have an amberline cross with an eye infection. I asked the vet and she gave me some antiseptic cream which I have used for week but it hasn't got better. Each day her eye is full of a creamy/yellow pus and her eye has turned opaque. There is a small white spot on her inner eyelid that seems attached but I cannot remove it.  After the episode with Billie  I cannot afford another eye operation.

Any advice, as usual, greatly received

Thanks again ANHBUC   unfortunately I couldn't open the link but I think it is my PC. Today the 2 pullets are still with me, they seem a bit better, both eating/drinking and their pooh is normal.  The amberline cross is not so good, her eye is very bad and she is listless, sat open beaked, and sounds 'raspy' .  I think I may have to take the plunge and dispatch her.  I don't really want to, I like all my chickens, and giving them names doesn't help, but I don't want her to suffer and any more vet's bills or expenditure is out of the question (so says partner!!!) I have never killed anything (knowingly) other than flies so this will be a big test. My partner says if I am to continue and breed etc then I have to do it.  I am going to put things on hold a bit first though as this is enough to deal with plus I have hatching problems (see new post). I really am p*****d off though as I treat my hens really well. They free range, have good food, some treats and plenty of fresh clean water. I worm them, give them Cider Vinegar, vitamins, poultry spice you name it and I am just having no luck at the moment. My neighbour buys 20 chickens every 6 mths, the most raggety bunch of creatures you have ever see, 50p each. They are penned in a  dark corner of their garden, no grass, hardly ever cleaned out. They get 15/18 eggs a day and when they stop laying, well you get the picture.
