Just like to ad something here for any one that will listen. We all should be doing test mating with non SOP fowl and keeping records just to verify what has been said in the past. When I started testing and breeding in large numbers I found that a lot of information I seen posted was very inaccurate. There is no way anyone can make an accurate assesment of the young with only 5-6 young to go by. I think a minimum of 25 chicks should be studied to make a decision on any breeding. If testing is done we will probably find that most of what we know now is not factural. there is so much that is unknown with chicken genetics.
I'm listening, Don............have paid very close attention to everything you have posted on breeding techniques. Not a spring chicken and not new to breeding, and enjoy very much learning from others that understand what they are doing
and are willing to share with other breeders, old and new.
I hatched out somewhere around 300 marans of 3 different varieties last year. Just starting to cull through the last ones that hatched in November.
There are precious few left of all the other hatches - cull hard and often!! BCM have had so many other things mixed in, and other varieties mixed in, and until a breeder hatches A LOT of chicks, you really do not know what you have!
It is a difficult variety to work with and get correct, and unless you can hatch a lot, you don't know what the person before you did - or didn't do!!
I'm up to the challenge, although I will admit I thought of tossing them aside more than once.............but I don't own any breeds that aren't a challenge to get to the SOP!
