Sounds about like my outcome. I had a few over 5 lbs. with an avg. of 4.74 which I was very happy with. After struggling with keeping them in brooders, and hauling them outside eveyday, I built a spacious structure with deep litter in a secure building and allowed them a ramp to go in and out. The most annoying part of that was the fact that they would not go back in at night without prodding from me. If I waited till after dark to go to them, most would be camped out up against the building on the concrete apron. I'd give 'em the boot and slowly they would ascend the ramp and go in for the night. In the morning, most would readily go out, but for five or six. I'd get my stick and poke 'em out the door. LOL Next time, I want to put another chicken with them to maybe teach them a few things.
Next year, I will raise the poults in the same enclosure under roof, providing them access to the outside at a very early age. I will have shelters and sunscreens for them to get under. I did notice that care must be taken not to have the young featherless birds sunburn. They will be outside away from a heat source much earlier next time. Autumn can present its problems with ever decreasing temps, so I'm hoping Spring will have the opposite effect. Once out from under the heat light, they will be able to free range a large yard, protected by electric net fencing, but will not be allowed back into their brooder room. I get giddy thinking of the amount of work this will save. My only threat will then be from raptors. I plan on stringing old CDs above their yard on poles to help scare off any aerial attacks, and I do have a large kennel with six yappy jack russells in the area as well.
I forgot all about the ACV! I will definitely add this to my list of next year's must haves. Mine got good, cold well water containing all the natural minerals, especially limestone. I think they thrived on it. I also tossed them garden scraps such as broccoli leaves, apple cores, etc. They did have large wet stools at times, and their water consumption was huge. I filled a 3.5 gallon waterer twice a day, and they generally completely emptied it each time.
I'm really looking forward to my next go 'round with Cx. I am very pleased with Welp Hatchery and the quality of the birds I received.
