Aloha,
I purchased 3 RIR pullets when they were about 4 weeks old. The person I bought them from did the best she could to try to sex them, but there is a definite difference between them. Two are much larger and have bigger combs and wattles.
I have checked out numerous other threads on this...
Aloha!
I live on Kauai as well and I am wanting to get some egg layers, probably Rhode Islands. I like all the different coop designs and am blending some of my favorite ones to come up with a design that will work for this climate.
For those of you keeping hens on Kauai do you have any advice...
