What is wrong with this chicken ??

[Kimberlybaker59]

i have this 1.5 year old chicken who started making this weird sound sounds like a race car cackling when she breathes in and out. no other symptoms that I can tell.. thinking it was respiratory I seperated her, gave injections of Tylan yesterday & today and no improvement yet. Now I'm questioning myself.i can't get the video to load.

Sounds like an upper respiratory infection.
