I have 5 Jap Quail chicks who were all developing well . They are being raised on non slip towels and leaf litter. On day 7 of life after hatching one by one over 24 hours they are all developing leg problems. First they walk with a penguin wobble, then it slowly develops till they cant stand, then when the are sitting the legs are back, front , sideways under them. They are still eating and drinking if put in front of them but basically they cant move. I splinted one and it ended up lying on its side and died. They are being feed high protein game crumbles and very fine shell grit. Help !!!!!!
