We were re-fencing our run yesterday, replacing old rotted wooden pickets with some welded wire material. Unbeknownst to us, one of my birds got herself stuck in a pallet and when we found her she had a very deep gash on her head from what we are assuming was a nail or screw from the pickets we were tossing, we found her after about 5 hours. I freed her and of course she took off running to be with her flock, who met her with tons of pecking and trying to get rid of her. I was able to catch her again to examine the wound and saw it was down to the skull, large and deep, and was still actively bleeding after 5 hours. I also believe the gash on her head was made worse by the birds pecking her for 5 hours while she was stuck. I made the decision to cull her. I felt fine about it yesterday but today I'm wondering if there was more I could have done for her.
