I have seven Welsh Harlequin ducklings that range in age from 5 - 8 days old. The temperature here has been lovely, lows in the 50's / highs in the 70's, since they were hatched. They are with their moms in a large house and large shaded run. The weather forecast is for temperatures to begin topping 100*F starting this Friday (three days from now) and continuing at least ten days. I am worried about them given how young they are and that they are too young yet to swim to cool down. I'd appreciate suggestions for their good care during the coming heat wave !
