Okay, so we are a very large family trying to make almost all our own food and actually with super hard work it has gone well! We are about to have our 14 th child, built own large log home and live on the edge of the boreal forest the prairie province of Canada! Years previous we bought and raised Grazers or what most people here call Rangers! 300 But we want to do this with our own heritage birds that we have invested so much in. I wanted to do all barred rock! But we had such huge amounts of rain and humidity last that we could not get down even with windows open and fans on we lots hundreds of chicks! Parasites thrived in this weather and grasses did not pick up mineral like they should from the ground just grew on water or flooded out. We had our barns flooding. Ground water table was right at the surface. So just left us with way less chicks even though we poured the coal into them. Effected severely our other livestock too! So I need to look at combining other breeds as well but need body mass as much as possible and fast as can be growth. As it is we cook three chicken up for a meal for our family. So I will do barred rock! I have 8 maybe 9 hens. Then I was thinking a barred rooster over 4 or maybe 5 white Wyndotte hens. (I bought white Wyandottes for meat as I was told they grow bigger than than BLRW I currently have and the GLW that I will have). I am not this is true, seems no bigger than their other color combos which brings me to the next breeding if there is no true difference. And that is also throwing my BLRW hens (4 to 5) maybe 6 as there are some splashes! In under the barred rock too! And lastly what about my biggest Maran hens under the barred rock rooster? Now in the statistics it says marten hens weigh more than the Wyandottes but I don't totally see this and maybe it is because they are taller more spread out meat to bone ratio. So is it worth it and will it grow fast enough! Reason for barred rock over everything is seems barred is faster growing and more meat type than any the others in stand Along pure bred. And we need to optimize this! I have Orpingtons but never in all the years have they ever amount to much meat! Huge birds but not the meat ratio the book say! I need dense and up front meat! Faster growing in terms of what a heritage can do! We need about three hundred birds and hope to to draw it out to more than three and at most 4 weeks out hatching. Because our season is short here to grow out plus want to simplify and not be chicks in so many stages. After we have our meat birds then they will be separated in their pure form and flushed out then hatched for purebreds to sell as day old chicks! Next year we should have enough barred rocks not to have to do this unless of course one of these combos produce an awesome meat cross. What do you think of these crosses do you think they could come out the same as a true barred rock or at least pretty similar that the difference is not really registered? Or do you think any cross will not even come close??? Thanks kindly. This has been mind racking and had last year Vern good we would not to consider this. But need to make use of what we have without more investment!
