Considering adding a rooster to our flock of five hens (18 weeks old, currently). Probably wouldn't do this until early spring, but am thinking about the best way to introduce one. Which do you think is/would be best? 1. Get one that's 1+ year(s) old? 2. Get one of similar age to the rest of the flock? 3. Get a chick? I'd really like to go with a welsumer or houdan, though my DH is more keen on a banty roo in which case we're both quite partial to d'uccles.
