OK , I already had the suspicion she is not a bcm , (swears a lot now lol ) . The parentage is indeed not easy to know if you see what breeds there were , they had and roosters and hens of every breed which makes it more difficult and certainly the fact they did not even know what all the breeds exactly were , some of them were just refered to as ' the one that is that colour ' or ' the one that is looking at the left right now ' , I did ask for the breeds but they were just as clueless as I am altough this one got listed as a BCM and I found her indeed quite pretty so I also assumed she was a BCM as they quikly showed them to me and I noticed the colours , now it was much darker in there so at first sight she just looked like a Marans to me but back home I already said to myself ' hmm now I see her in the sunshine I do get doubts about that one , is he really a Marans ? that is a very beautifull one then but she is I don't know , she doesn't seem to be what a BCM usually is ' , and few days later then I noticed the behavior was not like the Marans , she is defending herself if she has to and she is actually more flighty , I got stunned by her being so flighty actually . She does trust me and knows I'm the one that is taking care for her but each bcm just lets the daily return happen ( other hens too besides the barred rock girl ) and she is right away flighty as soon as I just enter the run and come near the coop , same applies for feeding her , a bcm eats it right in front of me while she just waits if I am standing too close ( I give the scraps always out of the hand and a part of it , for the ones that are not that petty I put in a feedingdish about half a meter away from me and even they approach then but she doesn't , she waits untill she notices I'm done feeding and cleaning the coop , so it is not that she is really frightened or anything , she is just not as tame , docile as the others , certainly not the behavior of a bcm , ALL my BCM eat either out of the hand or eat it when I put it in the dish as fast as they can be with or without me standing / sitting there and they are more petty , and really all of them , some more , some less but they are , she is not , plus all bcm's and other colours of Marans stay in a group together , always ! she is not hanging out with them , she hangs out more with the roo and is high in ranking in the flock yet not over the barred rocks

but she does hang out with them , the rocks , the roo and sometimes with the orpingtongirl that is lonely but never with the bcms

and I wanted to make sure they were no longer in such minority to defend themselfs a little bit more and have company , nope ain't gonna happen with this one

. So also another question raised my mind by reading your replies , wherefor I'm truely gratefull btw ! and that question is , she should be a black sexlink right ? even when she is some kind of hybride she still is a black sex linked or not ? because the BCM roo here already gave her a ' warm welcome to the flock , cheers , jump ' I would like to know what the youngsters would look like by the cross of my bcm roo (that 1 is for sure a bcm

) , just wanted to cross a Marans with a black sexlink but if she is a hybrid , is she still useable for a cross or not at all ???
I'm gonna have to wait untill the afternoon for pics as I gotto go to work but not sure when I can get home because on a sunday they usually don't like it when I take of . C u all later today with better pics ( this shot is taken in the garage for the first time opening the box and putted them on the place where the old broodycoop stands that was going to be restored so had to use the ' flash ' , my apologie for that ) have a good day / night all and TY very much !!!
