Believe it or not guys...UofAr is not the only promising source. There are a few people who are breeding competitive show standard Houdans that just aren't on byc or as dialed in on selling. They may not even be aware that there are people chomping at the bits and willing to pay good money to establish a flock with their lines. Let me go through my correspondence and research and I will post and we can compare notes.
I just sent you the breeder info for the person I found at the Congress. Someone told me there was a thread for the congress so I might hop in there too. Mr P Allen is into conservancy and is all over the internet with e-pets I think. He and Dr Bramwell have worked together from what I understand. Houdans, even the nice ones I have seen in here and from other shows, really are below weight and their type is a little too upright in my opinion. There is a man in here who posts pictures of his show winning Houdan from 'back in the day' who you might talk to. (fowlman01) A lot of people have given up on them till recently. The best way to learn what the size might
look like on a breed is to find a comparably sized breed for those visually dominant learners. Even LF Polish aren't heavy. You are talking Antique Rocks here. Go to the deli and imagine holding three or four of their tall, two pound containers. That would be what your bird should weigh. Now compare this with the upright, diminutive Houdans seen now and you can see how they have gone to 'carry on' size. Its possibly to breed them with Anconas, if you can find good ones of those (again tough but not impossible if you hit the shows or threads in here) to try improving their size. Its a 6 year commitment either way. At least.
I look forward to seeing what you have. I don't know where to look other than online. Google has led me to many hatcheries, informational sites, BYC, but no breeders/exhibitioners.
If you are serious attend shows and big ones that are likely to have the chance of Houdans being there. Walk in and get the breeder list. It will have the breeders info. I found Crevoceurs at the local fair but did not see one at the Congress. Also if there is 4H or a bird club talk to them. They have lists of members that aren't on line or advertising and then there are the folks they know who aren't into the club. Network
