One of our 4 week old serama chicks isn't walking. This has been going on for about 5 days now. She is the only one that acts like this. I figured she had botulism because I examined their chick starter and it had mold growth in it. I also found some bright green poop in the bedding. I cleaned out the brooder and got new feed. She eats and drinks well and walks to the food and water when I refill them. She is unstable and shakes. I feed her boiled egg every morning and they get medicated chick starter during the day. I have tried dissolving vitamin b12 tablets in the water. I also tried vitamin electrolyte mix that has riboflavin. She isn't worse, but she isn't better. Will she ever walk again? Should I do therapy with her? If so, how do I do that? I have been handling her a lot keeping her away from the others. I noticed that I haven't seen her poop. Any suggestions would be appreciated! Thank you!
