this past may13 we got a group of 50 left overs. out of those 50 we ended up with about 10 hens which we moved out of the "boys pen" at around 7 weeks. wound up looseing about 10 or so to coons before i could trap them all out. Today we took what we thought were the largest 12 roos, mostly bared rocks. i didnt get a live weight, i should have but didnt weigh one just after i had killed it. avg processed weight was about 3.5 lbs. not much breast meet but some meety looking thighs. LOTS of feathers. i estimate i had as many feathers (volume wise) from 12 heavyies as i did from the 25 ish cornish x we did this spring. we will let the others go for at least another 2 weeks. so our first batch of 17 week old bard rock roos avg 3.5lbs processed fed layer feed for virtually the entire 17 weeks (there were a few weeks of meet bird feed hear and there) not impressed with useing "dual purpose" large breed birds. while the cornish x have there issues, large breed arnt without there own. we are likely going to try a set of rangers next.
