ranger and broilers need to be processed by a certain date to taste good. are turkeys and ducks that way too? i'm planning on getting some pekins and narris and was wondering do i need to time the narris hatching date backwards from thanksgiving or can i let them grow and dispatch them at a later date (before they're a year old). also with pekins, i've heard the best time to dispatch them is at around 8-9 weeks. easier to get the feathers off. but will the meat be chewy if i let them go to 6 months and process them? thanks.
