It is SOOOO Funny to me that I came across this post!!! I have been searching and searching for what turns out was the WHITE holland chicken... I want a white, white-egg laying, broody, dual-purpose bird. It was sometime last week I decided I was going to start a breeding program to create a breed that fits what I wanted and have been doing TONS of research along those lines (all the way from where to get breeds I'd like to use to taking crash courses in general genetics and specifically chicken genetics, mapping out probabilities, numbers of generations before breeding would be true, desirable gene pool size, ideal traits vs undesirable etc. etc. etc. etc. etc.!!!!) Then today while continuing my research I came across information on the White holland available at a couple of hatcheries. Turns out it was just the barred variety the hatcheries carried but thinking the white existed I searched more until I finally came across a number of posts with the 'believed to be extinct' information *cry* That's also when I found this post and thought as a BYC member also I couldn't help but join in the conversation! I do not have plans to revive the Holland so much as to (TRY to) create a similar purpose breed since I've already done so much work planning "my" breed out lol I also wanted to make a couple of points...
Why "another" white bird? For me it's a double reason 1st Aesthetically I think white birds are gorgeous. It seems so rare in most breeds that despite the prolific numbers of white chickens it still holds that almost mystical, regal quality (like a white unicorn, or a white mammoth for anyone who's read the clan of the cave bear series.) 2nd I live in Arizona which is a VERY hot place and it is a dire necessity to find ways to keep our birds cool. White is a very "heat resistant" color and so is a very logical choice of plumage for birds being raised here.
Why not a White Game? Because White game hens are 2lbs smaller on average than a White Leghorn which is not considered a heavy bird to begin with, they lay fewer eggs on average, they are not able to bear confinement as well, and they are as a breed considered as more aggressive birds. Dorkings may not lay WHITE eggs, although "cream to light tint" might be passable, and they are docile, and adapt to confinement well and are very broody... they are also on the fragile & slow maturing side. Leghorns are flighty, they're a little on the light side and usually not considered dual-purpose (although it differs from breed list to breed list on that...) and... well, the list just goes on. Try doing a search here on the 'chicken breed selection tool' For a standard sized, dual purpose, med-high frequency layer, medium to large white egg laying bird. Only two appear, one is the dorking and the other is the Russian Orloff which when further researched has conflicting accounts of traits (such as light brown eggs rather than white and also called a "non-setter") and it is also on the slow-maturing side. Now repeat the SAME search only replace "WHITE egg" with "BROWN egg" and FOURTEEN breeds appear. (Fifteen, but one's a duplicate.)
That is why despite my currently very small poultry experience I've decided to give a breeding program a go: To fill that gap. Besides, I don't live in a city, just at the edge of a county, I have the time, the land and the desire. At the very worst my experiment won't pan out but I should have a very interesting flock If anyone IS INTERESTED in reviving the Holland though I'm definitely amiable to going in that route instead just to increase the genetic pool. I already have some Rhode Island Reds and White Leghorns (none of which at this time are of breeding age though LOL as I said... it's a new idea for me!)
