Well I opened it up and took some pics but i was in a hurry so nothing worth posting.
The first and second frames are pretty much glued together and to each other but are chocka block full of bees. The third frame is covered in bees both sides and looks straight, no warping. The fourth is also heavily covered on one side and lightly on the other. All these seems to be being filled and capped so all looks good.
The other frames need to be refondationed (?) so I think I will try to buy some already embedded.
One sheet of wax was lying at the bottom on the hive, acting as sort of a rubbish trap. There are lots of small white eggs and some 2mm long white thin maggots i think crwling around. they are as thin as a human hair and have brown heads and crawl like a catepillar with the back hunching. I suspect they might have been eating the foundation. Any ideas guys? They remind me of fruit fly larvae, just a spec.
Aside from that they look happy enough, thre were more in the hive than I expected, but i spose there are a lot more bees now!
