We have a 9 month old Pekin drake who seems to be sick and we cannot figure out what might be wrong with him. About a week ago my DH found him swimming and exhausted in the stock tank and he could not get out. My DH had to lift him out of the tank. Ever since that day he has seemed lethargic and he hasn't quacked once. Our other drake is quacking all the time. He seems to have stopped mating the hens. He's drinking but would not take treats from my hands today, Which is unusual. No other duck is acting 'off'. Any ideas what could be wrong? I'm thinking about starting him on electrolytes tomorrow. Any other ideas?
