I was fortunate to be given 20 fertilized eggs from a friend who has registered Show chicken champion Rhode Island Reds. 12 chicks hatched and all have survived & are now 12 weeks old. I can definitely peg 8 of them as hens - small yellowish combs, tiny to non-existent wattles, docile behavior etc. However of the remaining 4, I am confused !!! Two are large birds, prominent reddish combs, shiny looking feathers and starting to develop greenish hackle feathers. No real indication of wispy saddle feathers but just look like roosters. The issue is with the other two - both brownish, no really shiny plumage, yellow - pinkish combs & the one has its juvenile feathers still on its head. I recently enlarged their run by a further 6 sq feet. The two youngish "roosters" are now chest bumping, puffing out their neck feathers & acting all Kung-fu Panda pants. They only take issue with each other & the two large "roosters" simply ignore them. So my question is - Could these two just be hens having a bad feather day or do I now have two confirmed roosters? The two large "roosters are now acting even more docile than ever.
