9 week Speckled Sussex chick is not doing well. 2 weeks ago I put her and her sisters out in the coop (with heat when needed). She developed a cold. She was lethargic, felt feverish and was sneezing. Vet felt she needed antibiotics. Sneezing and fever cured, but now she will not eat! She sleeps 24/7, has no appetite, and has her neck pulled in with ruffled feathers. I have crop fed her probiotics, sav-a-chick, and pedialyte to keep her hydrated. The only time she will eat is after I have given her water via her crop and I entice her to eat watered crumbles mixed with applesauce. She then will eat a couple of teaspoons and then go back to sleeping. Her poops are totally normal and her crop empties over night. But she has no interest in feeding/drinking during the day. I have to work, so she is on her own, in a comfy cage, with a heat lamp. Last night, I crop fed her water with corid. She seemed to be more relaxed last night and ate easily from my hand. This morning she is no better, eyes closed, no interest in eating or drinking. The vet said I should deworm her. What should I use? Should I continue on with the corid? How long can she go on without eating or drinking? I am probably not giving her enough. How much water/food do 2 month old chicks require? I could crop feed her. I will have more time on the weekend, but I am at a loss as to what I should do besides supportive care with feed and water. Am I only prolonging it? How long should I give her? She has been refusing food for 4 days! So sad, she was normal in every way before she started sneezing. I do not understand what is wrong with her! Any help will be greatly appreciated! I need some hope and direction!
