I have Emdens and Pilgrims from Murray McMurray. I love them all but am worried about them cross breeding and ending up with mutts! I'm sure they'd be sweet but I want to help keep the lines seperate, just not sure if there is a critical time to seperate them or if they always have to be apart? (since we have a horrible predator problem, I overbought and now that I have cracked the nut on keeping them safe I have ended up with more mature birds than I thought I would have.) Also, if keeping one line is the way to go and selling/parting with the other, which one to keep? My primary interests are homestead geese to weed adn to keep off aerial predators like red tails/coopers which they have done fairly well thus far. Egg production is not really a concern. Just want them to forage well, stay at home, and raise their babies. thanks for answers on both questions!
