HELP! Sick chick

[tatipiazza]

Hi there, I have 4 chicks. All about 3 weeks old. 1 Astralorp, 1 Koekoek and 2 Boschvelder.
A couple of days ago the Koekoek had the one eye shut. All day. The other eye was open and she was eating and drinking as normal.
Following day same eye looks inflamed and still shut. Again, she was still eating and drinking as normal. Called the local vet who recommended we wait another 24 hours before bringing her in. Next day, eye back to normal, yay, but now she stopped eating, drinking and is acting very weird. Barely walks, keeps turning in circles sometimes and almost seems like a neurological problem. And I'm not sure she can actually see even though eyes are both open as she walks right over the food and water containers like they're not even there. Took to the vet, started on antibiotics. Her saliva also looks like snot.

Any idea what she could have? We isolated her and the Astralorp from the other two chicks but very worried that is is some highly contagious and they all get it.
Has only been one day of antibiotics, no difference. I've been giving her water with a syringe.

My kids are VERY attached to our chicks. Really don't want any of them to die.

Chicks can get respiratory diseases such as mycoplasma (MG) which can cause eye drainage and crusting shut, along with oral mucus or nasal drainage. That particular disease cannbe passed through hatching eggs or gotten through exposure to an infected bird. To treat neurological symptoms, you may use some vitamin E and a small amount of cooked egg for selenium, to see if that helps. Unfortunately, a sick young chick starting out may not thrive or have good immunity. What antibiotic did the vet prescribe?

Doxysyrup. She hasn't eaten since yesterday morning before symptoms got worse. Should I be trying to feed her something? I do give water every few hours with a syringe.

I would try to feed her some wet chick feed and a little egg yolk or scrambled egg bits. Watery feed can get more fluids into her. Doxycycline is a good antibiotic to treat MG or eye infection. If you can get Terramycin eye ointment or plain Neosporin ointment, that can also be applied ro the eye twice daily.

How are you Syringe feeding? Droplets at the beak area?
Please try crop feeding, attach a small flexible tube to end of Syringe. Get some solid feed into her crop.
I soak pellets, crumbles, add some boiled eggs and press through fine seize add vitamins and whatever meds etc , it's so fine it doesn't block the Syringe. Here is one video of how to crop feed. I just posted it in Emergencies forum too then read your post.
