Not to argue with the experts but on my octagon 10 the vents weren't that obvious, 2 x 5pence size holes at one end (no plugs supplied in my box - unless I missed them) which I used tape to cover to some degree to give less ventilation - again not very scientific but kept more humidity in for hatching

Thanks, I can see those now, but had no idea they were vents as I have no instruction booklet.  Will use tape, thank you so much.

Good luck Jo fingers crossed.  Ive 3 fluffballs (out of 20 eggs) this morning.  Have to see what today brings.
