I have 19 EEs. I believe 8 are pullets (I posted pics in another post) I am fairly confident that 9 are for sure roos. I have 2 that I do not know but I believe they are roos. All are 17-18 weeks old. The 2 in question do not have saddle feathers or long tails or curving to the tail yet. The neck feathers are different than the pullets. Their combs are wider than the pullets but are still small and pinkish but I can not make out more than one row or just really wide. They have some 'spikey' feathering starting on their heads. Most of the pictures are them together since they are always together. We call these two Neapolitan because the heads, body and tail are all different, one with a black head and one with a red one. Tell me your thoughts?
