Your picture isn't showing up....
Plug your camera into your computer... access it and copy the pictures you want to post into a folder on your computer.
Then.. come back to BYC, signed in, next to Recent Posts is Upload.. go there.... click on BROWSE.. find the folder on your computer with the picture in it.. click on the picture... (the file location will show up in the box)... then, click on UPLOAD. Now, you cannot close that page until it finishes uploading.
The only problem may be that I think you have to have a certain number of posts before you can upload pictures.
If she was sick already, got weak, then the others would or could attack her... I had one young hen "murdered" by the others -- I didn't isolate her as she was getting better... but, they killed her because she was weak.
You might give her some antibiotics in her water as well... just in case she was sick before they attacked her.
Good advice to take from dawg53... that's the right process / action to take.
Good luck.
