I now have 5 female and 3 male ducks. They are 6 months old. When will the females begin laying? Also, they are housed in a 100 sq ft coop with my 15 hens and 1 rooster (Bantam). They sleep in an area under the 6 hen nesting boxes, so I'm guessing they will lay their eggs there? Also, do all female ducks 'laugh'? It does keep my husband and me laughing.
