I have some Buff Orpingtons, 2 Americaunas and 2Rhode Island Reds. I got them at the same time and at the same age, yet the Rhode Island Reds seem to be smaller than the otheres They are about 5 weeks old now. Is this normal? I thought RIRs were a heavy breed like the Orpingtons.
In general, RIRs are smaller than Orpingtons. There may be exceptions, but Orps are supposed to be very large hens and roos.
Hi "Pipit," I'm raising a flock at the University of Rhode Island with some RI Reds and Aruconas among others, and these are my growth figures for the first few weeks; hope they help. Week 1 Arucona: 75g RI Red: 63.5g Week 2 Arucona: 140g RI Red: 141.5g Week 3 Arucona: 220.5g RI Red: 216g -Kate
