I've got six going-on-three-week old Muscovys that I will be putting outside next weekend. (Daytime only for a few weeks.) I've read that exposing young hens to long daylength makes them mature too fast and lay too early. The days are now about 14 hours long (6 am to nearly 8 pm). Is the extended light a concern for natural daylength? I'm really not crazy about the idea of keeping these guys in doors for 3 months.
