I just got what appears to be Khaki Campbell ducklings x 2. I have them in a tote with water, food and on paper. I originally had them in with 4 new chicks on pine shavings but they kept eating the shavings. One is already a mama's baby, if I sit there and watch them they will sleep, but if I walk away one starts peeping almost none stop. Any advice for a new duck mama? How warm should I keep them (not certain about age)? Any special foods or treats?
