My poor birds! I returned home to the rather unpleasant news that the idiot petsitter we hired was feeding my birds wrong. Instead of feeding them seed, she fed them pellets, which they do not eat as their main staple. Luckily, we were only gone two days. If we had been gone any longer, they probably would have died.
Tomorrow should be interesting, as we have to meet with said petsitter to pick up the house key, and said petsitter does not yet know of the wrong she committed.
