Ii have the opportunity to go to the Netherlands for 5 weeks (August 10th - September 16th).  I have 2 hives - one strong and one with maybe a ?newly hatched queen (picture below, taken July 23rd, so would be anticipating brood August 15'ish).

My question - what NEEDS to be done while I am gone?

• I am assuming feeding, if the weather continues to be hot and nector sources decrease (not thrilled hubby may/will do).  
• No brood in the weak hive, so no need to check for mites.  But, do check for the strong hive.  
• Anything else for while I am gone?  Or, any suggestions for when I get back to make sure my weak hive has a better chance this winter?
