The crew should be arriving Friday and I'll keep them inside a bit to make sure everybody is eating/drinking doing well. During the day it's getting up to 90 and at night it goes down to 70...maybe mid 70s. I have a secure place for them outside in the pen (enclosed and protected from rain) and have a heat lamp for the night, is it possible for me to put them outside at about a week or so? I'm raising these for a friend and she ordered 30...I don't have room inside for 30 ducks! Luckily we are all sand here and the drainage is great in the duck pen. When they're old enough to have the pool all the time they can't make it muddy.
