Sick 2 week old chicks

[Therese Brown]

Good evening. Any help would be appreciated. I have 4 2 week old opal legbar chicks that are showing signs of congestion and are sneezing. I got them a week ago and they just started showing these symptoms today. I have la 200 injectable but I'm not sure how much to give baby chicks. This is the 1st time this has ever happened to me. Any suggestions?

200 what? Tylan?

My 1st time ever experiencing chicks this small getting sick. I am very careful with handling them. I wash my hands before and after handling them
