Hi, My two silkie chicks are 16 days old. They are active and eating well. These are my first chicks so here are my questions. They feel light and boney, is that normal? Their feathers look very scraggly, is that usual at this age? They have brown runny poo on and off, feeding Dumar chick starter. I purchased a first aid kit at the Northeast Poultry Congress (chicken whisperer table) so I can treat them, but not sure if I should.
