I kind of did mine in reverse in terms of protein. They got chick starter for the first 2 or 3 weeks, which is at 18% protein. There were a few heritage chicks in the brooder with them, so I wanted to give a more conventional feed. After they were with the main flock they got purina flock...
Starting at around 3 weeks, they only had access to feed during the daylight hours (they had to leave the coop for it). Days were long in May when I was raising them, so basically they had access to the outside and the feeders from 5 a.m. to 8 p.m.
I think you will be fine. They do grow fast near the end.
Caveat: it depends a bit on how they are fed/keep, the strain of CX you have, as well as your goals. Some strains grow faster than others, but in my experience they are breeding for faster and faster growth.
To relate my own...
I personally butcher any heritage type cockerels between 13 and 16 weeks old. It depends a bit on how you plan on cooking them, but that to me is the sweet spot. They are not yet creating total havoc in the flock (fighting, chasing hens), yet they are big enough to be worth the butcher, plus...
Morrigan is now at peace. We looked in on her around 8 last night and her head was still up, she was alert and she looked comfortable. This morning she was in the same spot but her head was down and she was no longer with us. It looked like a peaceful end. I’m very sad, but also very...
This isn't a post looking for advice on a cure, but more sharing my thoughts (and grief) upon reaching that point where you know there is nothing more you can realistically do. I put it here because so many who have searched for, or offered, help and cures on this forum, eventually reach this...
In my 12 years of chicken keeping it's happened to me twice. First time, I found a 1 year orpington dead under the roost. We had a big storm that night, and my best guess was that this was a factor but I don't know. All other chickens were fine.
Several years later it happened again to...
This is very interesting. I take it that this is a video of your set-up. It looks like you basically lined a hutch/cage with cardboard boxes. What type of dirt is in the boxes, and what is the poop cleaning process like?
We used to keep rabbits, and still have the old hutches. I keep...
I've always given my CX spare produce/weeds/table scraps/fodder. I scatter them about the yard to encourage them to get up and move. It's always been a relatively small amount of their total diet (less than 20% at most). I've never had any issues.
