This has to be my worst experience raising chicks, I've had 5 die so far despite never loosing any before. A few that died i understood why but one of the most recent died due to injuries to it's knees, it was cut and swollen and the chick couldn't stand.
I've got one with a knee that's swollen 2-3x normal size, i thought slipped tendon but I'm 2nd guessing that now. I've also got another one that had what looked like open blisters behind it's knees so treated it but now one knee is swelling and it is losing motion, does anyone have any idea on what is going on here?
I'll be adding pics shortly. Can you tell us a little more about the injuries/cuts that 1week old chicks got, how did this occur?
You mention in your original thread that 5 have died, did they all die from the same leg/joint injuries?
If all of them have the same symptoms / swelling/lesions on the hocks and they were all injured/cut, then infection could be the cause.
