In advance thank you! Nine 10 week old chicks that I got from the coop in may. About 4 days ago I noticed 1 or 2 sounding hoarse or like a duck. Thought it was from the hot weather we have been having, 90 and humid. Today it's in the 70's. No other symptoms that I could tell until today. I went out this morning and called every chicken. Everyone came but my poor little Sussex was running from across the yard limping, stopping every 5 ft with her mouth open and definitely in distress. I picked her up and put her in a dig crate in a quiet spot. Started antibiotics, vitamins, hydration from a dropper and encouraging food. I quarantined the rest of the chicks and started the them on antibiotics. The rest of the flock seems fine (7 adult chickens and 4 nine week old ayam's). They all sleep in the same coop. Here are a few videos.. any help is appreciated.
