I was aware of the need for low roosts, but had not considered the possibility of "perceived competition" or it's effect on fertility. Hmmmm. I'll need to ponder on that. Does this approach in housing increase aggression towards humans in any way (redirected aggression?). I've got a one year old son who loves the birds - I can't/won't keep aggressive cocks for that reason (which I openly admit is going to further complicate breeding efforts). So I may need to continue to research layouts and building plans to find something that will work for me and the birds. There's no one correct answer out there, I just want to plan as best I can to improve my odds of success.
The juvenile males pre-crowing age could theoretically be housed communally, though (with the given exception that there's always at least one who can't get along with anybody)?
I've never had an aggressive Orp. In nearly 15 years breeding buffs I can't recall even one. However a one year old child is much different than a larger child or adult. That'd be your call there. Personally I wouldn't let a 1 year old on the ground with poultry of any type. Accidents could happen to fast.
