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.
