omg she dose look vary scared!!! try giving her warm water. which might help her to calm down. if she dosent drink try feeding her some bread. i know most people will think this wont help but i have a feeling. is she hot? that might be why shes breathing lots?
i think she might have.. you sould bring her inside maybe? last time i had 2 chickens that were sick i thot that the one could make it out side so i just brouht the one in and the other one out side was dead. so really try your best.. belive in god to keep it alive. god knows wather its her...
well it sounds like this little chickens having a hard time.. maybe it broke something. or maybe it is in shock.. if you really dont want loose her then try warming her up and feeling her joints. get a vet if avalable. 40% of living. and 60% of not living for this chicken
