Hi fellow chicken lovers. I am entering two roosters iand four hens in the county fair-roosters are Rhode Island Red and Barred Rock. McMurray Hatchery has numbered bandettes which I need, but I can't figure out what size for these roosters. Plus I only need 2 for these roosters. Size 11 or 12 is the biggest I think. Can someone help me? I guess I will have to go ahead and purchase the size for the hens but I can't judge for the roosters. It is expensive to buy these bags when I only need 4 for my hens (1 RIR, 1 Barred, 1 Jersey Giant, 1 Buff Opington), 2 roosters--1 RIR and 1 Barred. Any one have just a few? Thanks!!
