If there are any recessive genes, the breeding pair must both have it to show the problem. I had been working with my own line for several years and introduced a new Cockeral from someone else's line. Bred him to several of my hens and they produced some beautiful offspring, nice dark eggs, very exciting!!! Next season, bred the Cock back to four of his best daughters. Started hatching white chicks with the bcm coloured chicks. The new cockeral had a recessive white gene which he passed on to 50% of his offspring unknown to me until I did the father/daughter matings. When breeding him back to his daughters that had inherited the gene, 25% white chicks hatchedthank you @downtheriver !
Are there any bad things that pop up regularly with Marans when inbreeding? Like crossed beaks, or whatever?
This is only my third year hatching Marans, and I haven't had any genetic issues... but I haven't done any in breeding at all.
Some told me I had been given a gift, do something with it or just cull the whites, the correctly coloured ones were still BCM and the whites would still produce BCM if bred to another male without the gene (but 50% of all offspring would carry the recessive white). It is my personal opinion that BCM have hidden genes and it is important to inbreed so that we can identify and get rid of them. I am currently test mating two of this cockerals sons and hoping that one did not inherit the gene. If one is ok, I will be breeding him back to 3 of my original hens that I know do not have the gene, essentially starting over but knowing I have rid my flock of this unwanted (by me) gene. If they both have the gene, I will still breed the best one back to the original hens and then have to test mate any breedworthy cockerals again and eventually get one that does not have the gene. Only then will I feel I am on my way again. My birds have great type, colour and egg colour is getting darker and darker so they are well worth working with. Not giving up and not getting another cockeral for the chance that, heaven forbid, I incorporate yet another hidden recessive and spend another two seasons breeding to find out. There is comfort for me in knowing what I have. It is just going to take time and after all, they're just chickens
Again, just my opinions and experiences.
