I'm glad to hear she is a little better. It is good that she was vaccinated for Mareks. Sometimes vaccines do fail--some say as much as 10% of the time with Mareks. Also, if someone has had Mareks in their flock, then vaccinates chicks, those chicks must be kept isolated from any contaminated area for 1-2 weeks while developing immunity. I am so hoping it is just a vitamin issue--they are pretty common in chicks.
Was just hoping for more improvement after 3 days on polyvisol. Can someone advise me on adding it to yogurt (which kind of yogurt, how much, what type of container to offer it to her in)...she's getting too stressed with me trying to give it to her in a dropper. Also can I use save-a-chick in conjunction with the polyvisol treatment? I just want to cover all my bases and get this girl well! Here are some pictures of her legs. I don't know what I'm looking for but maybe they might tip off a red flag with someone...or not. She won't fully extend them when standing. She is 16 days old today.
