Question: *Too much Calcium* could be the cause of leg problems leading to the inability to walk (& death)?? I had 2 Banty Cochins & 1 Silkie die with this...my heart breaks each time. I feed them poultry starter crumbles (won't eat pellets) & crushed egg shells. The starter is made by a local feed store: 22% protein, Calcium min 0.8% max 1.3%. Any advice is appreciated!
