This is my first time on here. I have a lovely Wyandotte chicken, 18mths old. She's a big girl and amazed me with how heavy she normally is to pick up. ( I have 5 others of mixed ages & types.) A few days ago I found her lying on her side in the garden, she let me pick her up so I brought her inside, kept her in a cage and offered food, she seemed ravenous. But she has lost so much weight now. She had bad smelly diarrhoeah. After eating she perked right up. I've kept her in for 2 days, started 7 days of worming with flubenvet (and also for the other girls outside,) shes eating and drinking but does keep closing her eyes standing up. Poo seems bit better. I let her back out today, she seemed ok, not eating as much as the others. I chucked some food out for them,as they ran over she fell over and stayed there so I've brought her back in again. I think she's just weak from loss of fluids and body weight from diarrhoeah. My other half is against me taking the chucks to the vet as it cost £60 last time. Is it possible to get antibiotics any other way if that's what she needs? What should I feed her to help her put on weight quickly? I really want to get her better, what should I do?
