For see but don't touch integration it's generally 1-2 weeks, with the birds being able to see each other the entire day. 1 hour doesn't do anything because they never get a chance to get used to each other.1 hour a day. Doubt it. Unsure how to make hiding places

Also to clarify, beak clipping isn't what you think. They do it in commercial settings to prevent birds from cannibalizing each other due to crowding and stress. The beaks are cut off through the core of the beak to prevent it from regrowing (it's like cutting through the quick of a nail), but it also makes it much harder for the birds to eat this way (imagine if someone cut off the front half of your lips, would you be able to eat like that?) Absolutely no reason a chicken should be debeaked in a backyard setting.
