Just an update on my two separate batches in case anyone is interested in knowing how fast their birds mature.
Gordie's birds are lovely and very large, and began to lay at around 25-26 weeks. They are sweet natured, curious, healthy, and easliy handled, even the roo.
Duane's birds are a bit smaller and very SLOWWWWWW to mature. REALLY slow!! They are 31 weeks at the moment and only one is getting red in the wattles and comb. They are also very healthy, curious, but more skittish and not as easily handled.
Neither group is flighty at all. I've never clipped wings and they don't even attempt to fly, though one likes to perch in our apple tree, which has brabches that are about 1-1/2ft off the ground.
I also have some other RIRs from Joel Gilman. They are also slow to mature, are 32 weeks old at the moment but starting to redden up quite a bit. So I'm hopeful!
