My 10 week old ducks take neurotic to a whole new level. It took them five days to use the new tub we got them. Now they are not eating. This coincides with us putting a tarp over half of the pen to provide shade. They ate cuke & melon that I threw to them but did not touch the greens I put in their water (which they usually gobble up). Could it be the heat? The tarp? This is the third day. They seem fine otherwise. Also, I want to let them free-range when I am home but they won't leave the pen. I open it every day, leave a trail of snacks, but nothing. One got as far as the threshold one day but then we put the tarp up so now they don't go near the opening! I suppose I just need to be patient. I am new at this. It seems like one step up, two back. I can get one to eat from my hand one day and then they are all skittish the next.
