Hey I have a pair of ducks. They have a 20’ x 16’ enclosure with plenty of water and food plus a refinished dog house they call home. They don’t really come out of there coop except early in the morning and late at night. I don’t know why... the enclosure is hardware cloth completely covered and there are about two feet of wood all around the bottom to keep them safe. I don’t want them to be afraid to come out. Should I block off the sides so they feel more secure?? I don’t know what’s wrong. They are my first ducks so I’m at a loss. Any help would be appreciated thank you.
