I've got some Dk Cornish Bantams that are nearing 6 months of age now. The boys have been "practicing" their crowing skills for over a month, maybe even 6 weeks, and aren't even CLOSE yet. My Lt Brahma roo got it after 2 - 3 weeks! So I'm starting to wonder if they'll ever get it right, or if I'm destined to hear the "rr EE rrr rrrr" sound forever... I know Cornish mature a little slowly, but this is bordering on ridiculous (but cute at the same time).
