I'd like to chime in too, here is my quote from another FR thread
"I just finished butchering my first ever Freedom Rangers. They grew so fast and became huge. They reminded me of veloceraptor.
They were from Freedomrangerhatchery.
26 arrived, 1 died @ 1 week from unknown cause, 1 blew away in a windstorm their second night outside, possum ate another, 1 went lame at 7 weeks, 1 rooster was a runt that was only 3 lbs. 8 oz. at 11 weeks. Other than that all went well.
I fed 24% protein flock raiser till 8 weeks then switched to 15%.
Killed 3 at 6 weeks - they averaged 3 lb. 1.3 oz.
At 8 weeks they were 4 lbs.
At 12 weeks they were 5 lbs. 5 oz.
They were on pasture from 3 1/2 weeks on - they didn't like snow much though.
I was very pleased."
p.s. I butchered the lame one the day I discovered it.
I put an IR lamp in their house out in the field for the first couple weeks. They really didn't seem fazed by the cold.
Their house was in a hoop pen over one of my garden beds that had a cover crop of oats, wheat, field peas, buckwheat, winter vetch and some red & white clover. They wiped it out pretty good.
Their house was an A-Frame with both sides of the top galvanized roofing hinged to open up for access. It had the south side open with just hardware cloth. That windstorm came in from the south at night, blew the doors open and was followed by rain. I didn't realize it till morning. They were out there hours exposed to the conditions and no ill effects.
2 1/2 weeks
4 weeks
6 weeks
10 weeks
11 weeks That's the runt rooster in the middle.
I also think they were smarter than my hens who can't find an open door in their tractor if there are chicken out of the tractor on the side opposite the door.
The door into the FR house was a drop/drawbridge door that was quite high. Too high to just jump in. I noticed one trying to get inside, there was a railroad tie under the door and a brick on that. It looked at the RRtie and then at the brick, then at the door. It stepped on the tie then the brick and hopped onto the door. I could see it planning the route. Pretty wild.
From the time they were two days old the word that came to mind when I looked at them was - robust.
