I would personally choose the Silkie. I'm not a big fan of roosters as they are often aggressive and don't lay eggs, but I've had Silkies (including Silkie roosters), and they are adorable, sweet, gentle, friendly, and funny little chickens, and the Silkie roosters are nice roosters (as roosters go). )
Hmmm...tough call here. Some may be sweeter than others, some are prettier than the others. But I guess it is a toss up between #2 #3 and #6. Number 3 could be a wild one but he sure is pretty! LOL
I would have to go with the silkie. I use to have a silkie roo and a half silkei roo (his son) and they were great. Sadly as most rosters go they died protecting the girls.
But I would love an EE Roo. My current roo is an EE mix. SO Sweet.
