I'm definitely leaning towards cockerel, but sometimes Wyandottes can fool you. Could you post more pictures in a few weeks? It should be easier to tell by then.
I'll post in next week. The waddle started showing a week or two ago and cone week or so before hand. The other 3 don't look this one so figured roo. Have 39 other little chicks was really the only one seemed off from being pullet like store said.
