I need to know how to build a duck house and run for 4 duckling fast and cheap. May be other materials that could be used to build one. My biggest preators are raccoons and cats. I know I can use a kiddie pool for a pond. My back yard is fenced. No shed and no garage. Please help me I really, really really want to keep these ducklings. They are 11 days old. Thanks so much. Anne
