G'day all. We've had 4 splayed leg problems with chicks since June. Definitely not calcium as they get supplements int their daily water changes, plus we supply plenty of grit & cuttle. We suspect there is a genetic factor at play from one breeding pair that has produced two splayed legged chicks that failed to respond to treatment & had to be euthanised. There is a fair bit of wood shavings present in the wooden nest box. Of the two other birds, one recovered successfully & the other has nerve damage to the right foot which appears to be giving the bird some pain. Currently he seems to be managing, feeding, perching & interacting okay, but we are assessing his quality of life over the next week or so. Many thanks for the advice in this forum, been very helpful. Cheers Craig.
