I used to raise Barred Hollands from Duane and they should be very nice birds for your foundation stock. They should be close to the standard I saw his breeding stock about 3 months ago and they are nice quality. I had them for about 5 years, usually raised about 60 a year. You will do good by line breeding them, double mating is not necessary. I would consider and recommend them to any one interested in a nice heritage breed. They are great birds, mine were happy and healthy. Males did run about 4 to 1 at hatch. You can sex them at day old as the males are lighter in color by about 2 shades like a Dominque. There are good pics here the little guy in the center at the bottom is a cockerel. http://www.feathersite.com/Poultry/CGD/Holland/BRKHolland.html They were probably one of the nicer breeds for overall temperament, vigor, personality and hardiness I have had in the last 20 years. We have been having a very old fashioned winter here in tropical MN. I think it is the year of Heritage Winter. Last Sat. we got another 20" of snow followed by 20 to 40 below windchill for three days. Once the temps get back to 20 or 30 above I am planning to get over to see Duane and take some pics for the thread here. Oh boy 7 more inches of snow predicted for tonight and tomorrow. Good Luck with the Hollands. Charlie Christmas is coming and so is Santa Bob. He has been watching you.
