Bees don't seem to be following mechanics. I'm just starting to learn about them and attempting to creat a farm. All of my bees keep leaving the nest and not returning. It's been 10 Minecraft days and have not produced any honey. There are three bees constantly flying around the hive but never entering, all of the other bees (approx 12) have left all together and never returned. I don't know if this is an intended mechanic or if it's a bug but everything I've read so far seems to suggest that bees should not behave in this manner. 

I am on the beta version but do not have any beta functions turned on as I'm on my main survival world.
