Bees should be able to breed by themselves so I don't have to do it myself, saves time for some players.

In the current version of Forestry you would normally combine two bees in one housing. These will breed automatically and in some cases result in a mutation and give a new spicies. This can already be automated. Maybe not too well in Forestry alone, but there exists a lot of very advanced logistics mods you can use. Even BuildCraft could work.

What part of this would you want to change?
