Dog attacked Chickens - no visible injuries but they are not active

[Saraley]

My five year old accidently left the run gate open and the chickens were wandering early this morning. My husband heard the dog making commotion and went to check and he had 2 chickens pinned down. He was able to get the dog off them and return them to the coop. One seems to be unharmed the other has no visible injury besides missing feathers but has sat in one spot since being returned and hasn't moved. Once these 2 were returned we realized there were 4 other chickens still missing. 3 of them we found and appeared unharmed and were returned to the coop. The 4th I found buried in my strawberry patch - I thought it was dead at first bc it was not moving and laying flat but when I got close I realised it was still breathing and making soft noises. When I picked her up she became alert. She doesn't have any visible injuries on her and when I put her in a seperate pen with food and water she got up and drank some water. She has moved around some but is mostly sedentary. Is there anything special I should do for the 2 chickens that appear injured? Do you think they will be ok??

Hopefully they are just in shock and no internal injuries. I'd give them some vitamins/electrolytes like nutridrench or save-a-chick and check them over thoroughly for any swelling or bruising.
