I hope you are well now. I have been wanting Blue Birchen for a while but not enough room. I have trouble with my Marans roosters combs freezing. I have put up a heat lamp so I hope it helps.I have set up my blue birchen pen. I'll get some pics when I get a chance, but the sun sets around 430 right now and it has been rather cold in Montana. A few cocks might loose a bit of their Combs to the cold this year! Anyway, I have Jack over 5 splash ( supposed to be from a birchen pen, but could be hiding copper too and I would not know) and two blue birchen. Jack is a silver birchen cock, I think there's some pics of him on here. He's from my original line out of Rodney Reeves, who had to cut back on birds due to health not long after I picked up some of his lovely birchen Marans four and five years ago. My biggest issue I've had in this line is the carnation comb, but I've got a handle on it now. Besides that issue, I've been pretty darned happy with them, but wanted blues too, so now I'm about to produce my own line of blue birchen Marans this year. Super excited!
