HELP! What is happening to my chick

[tjogowin]

Seemed wobbly for a few days then sitting on hooks, now her/his legs are completely out in front. What is causing this. She/he is 5-6 weeks old. Was eating and drinking really good up until today. Please advise what I should do. Thank you

Sorry your little one is struggling. Has she been vaccinated for mareks disease? Has she pooped at all? Did it look normal? If you pick her up and set her on her feet does she stand or instantly fall?

I would give a b complex or super b complex tablet or capsule, 1/2 of one daily. Riboflavin deficiency can cause this. You can use a chick chair or chicken sling for periods if needed to keep the chick upright and make it easier for it to eat, drink and poop.
