have never seen a frame feeder... my dad and I made my miller feeder between us.I use a frame feeder so no ventilation issues...
Fera have just pushed out the enclosed. If you register on BeeBase and check the box to receive e-mails from them they will send you things like this.
What the leaflet does not give is much indication on timing for feeding but down here in South Devon there are plenty of people who start in late August. The timing depends on the amount of forage and how many stores the bees have. Mine were running very low so they all being fed now. They also have a thymol treatment at the same time.
thanks for the pics of your frame feeder. so the bees crawl through the hole, sit on the bits of wood and can drink the syrup, correct?
The bees climb through the gap between top bar and the sides of the feeder - see Picture 1 - which shows it assembled..
In a TBH, the space above the bars is blocked off from the bees.
The hole in the top is for refilling ... normally closed by a small piece of wood.. to keep the brood nest warm.. see Picture 2
