I am new with having quail. I hatched them out and got 43 of them out of 66 so I was surprised of the outcome of how many actually hatched. However they have been outside for weeks now however I was cleaning out the pen today and noticed one still in the box. My fiancé has found some before. It was in a ball like form. I thought it was dead I grabbed him and he didn't move any part of his body except for his neck. He opened one eye and his neck kinda twisted like in movement I laid him down and he moved his neck some more and his eyes closed. I left him there to see if he would move and he wouldn't unless I picked him up. Than he would move his neck again in a weird twisting way. One eye open again and than stay still again. So this is not the first time apparently this has happened it has happened to 3 of my chickens in the course of 2 years so I figured maybe something just happened to them and I know animals die. However it does concern me and I wanted to know if there is something actually wrong with my flock..? Please help!
