I have had Orps for years. We have shown them, bred them and loved them. I have kept them for over 15yrs because they are such a wonderful duel purpose bird and the show birds are still nice utility birds. About 2-3yrs ago I bought a line of Blue Orps I have played hell with ever since. Fertility is not the best. Yes, I do trim the fluff on the rear of the birds I use for breeding. Yes, their diet is wonderful and they have allot of room to graze, catch bugs etc as well as being on a good feed. They get produce year round as well. If I load my table top incubator with the 42 eggs it will hold, I can count on about 15 or so of those being not fertile. I can count on about 5 or so coming to term, maybe even pipping a bit, and dying in the shell. Out of 42 eggs I get about 25% hatch with the rest dying either full term or some where along the line. I have always used Hoovabator, and I have always had Orps. I have never had the issues I have had since I bought this flock. I love the birds they are very nice quality, however if I can't get hatches, they really don't do me much good. Any advice? Also is there some lines that are more productive then others? a large blue I could add to this line? I will add this is a 50/50 UK US flock if that matters?
