Daniel,
Have you raised many of the malay bantams you got from Doc? How do they lay?
I only have one bird from Doc, a stag. I didn't really intend to breed them, I just wanted a cock to cross into the Kraienköppe and opted for the Malay bantam stag for a few reasons. First reason is size, I figured a large Malay cock would be too large for the hens possibly resulting in a injury as can happen with big birds and it can
sometimes play an effect on fertility if too great of a size difference. I was told the Malay bantam line has an issue of being too large so crossing them with the Kraienköppe may possibly help in increasing the size and perhaps type as well; I've been told before Malay and Kraienköppe type is different, but I read a old APA Malay standard (given that I don't have an APA book because I haven't had any breeds except the OEGB I used to raise that were recognized other than the Shamo which I didn't want to follow the APA on) and compared to the Dutch Kraienköppe standard to find a lot of similarities; I've also got the German Kraienköppe standard now thanks to some German contacts.
I did this also because of the low egg laying capabilities Oriental hens, especially Malay, are known for. Another reason is the Kraienköppe cockerels not being very game I was afraid a game hen his size (or possibly larger) would injure him/render him incapable of breeding. I actually have seen one of my Shamo hens run off a full grown cock that was not game before so a Malay would be no different.
Another point is general belief of a lot of breeders are, the hens are the type. Meaning a Oriental cock over a Leghorn hen will produce Leghon typed fowl (though they will have some Oriental characteristics no doubt), Leghorn cock over Oriental hen will produced offspring more closely typed to Orientals "supposedly". It has proven true for me at least in my experiences. So a Malay cock will influence type in areas such as comb, leg color, perhaps small wattle/earlobes, color, and so on of course.. But the offspring should generally be more like a Kraienköpp coming from the hens while also being better layers/able to breed more hens to the stag and produce more offspring than one Malay hen inabling me to cull more severely hopefully speeding along the process. Malay are also part of the Kraienköppes heritage, so it makes me feel better I'm not adding any foreign blood so to speak. Right now the young stag was right at 5 pounds (I think something like 4lb 12 1/2oz last I weighed earlier this year) which isn't too far under the Kraienköppe weight range (5.5-6.6 pounds in cocks). Hopefully he'll help in throwing larger birds if mine happen to be too small, I plan to weigh every one of them once they get good size to check if the average 3-4 pound weights are right.
I can't answer on how well his bantams lay, you'll have to ask him about that. But nonetheless, the little stag is a awesome little guy in personality. If I suggested anyones Malay bantams to anyone out of the stock I have seen I vote Doc's birds even if as he said at one point on the other forum that their tails can be a bit high (as my stags is, which I am hoping will help in the Kraienköppe type).
God bless,
Daniel.
