I've taken on 2 female Muscovy ducks today. I've never kept ducks before only chickens. I do have a Pekin male who is also free range and spends most of the time in the river and comes to my back door at feeding time. The 2 Muscovoy's are 9 months old and currently on my patio where they seem to be comfortable. How long before I can open my patio gate and let them live like the Pekin fella? Thanks for any advise.
