I KNOW this must have been discussed previously, but a quick search turned up nothing. Can someone give me a short and sweet answer to when is the right age to process an embden? I assume that, like ducks, there are optimum times based on pin feather growth, but I'm mostly interested in is maximizing efficiency; ie, processing at the largest size possible in the shortest amount of time. I mean, if they reach their max weight in 10 weeks, there would really be no reason to keep feeding them until Christmas, right? But if they really keep putting on weight for a long time, and it's not just accumulating fat, there might be a reason to keep them longer. This is all assuming, of course, that I haven't totally fallen in love with them and change my mind about keeping them around...
