Hencam.
If you are between chicken flocks, as we are, this makes a decent substitute. What is really interesting is the night-time viewing, made possible by some infra-red dealy. You can see that the hens do not just snore the night away, but rather have cycles of sleep and consciousness, perhaps sleeping more than being awake, but still there is more activity than I would have imagined. By the way if you are viewing this cam from places other than the UK, be aware that the time difference will affect what you see. So, if you are in my homestate of Oklahoma, if you check in at suppertime, you will see that the hens are in their beds. (well, on their roosts, then).
And as a side thought, you can use this hencam for your lessons about latitude and seasons, etc. If you check in in December, around 9:30 a.m. CST, you will see that it is nearly or completely dark already over here at 3:30 p.m.! Conversely in June if you check in around 3:00 p.m. you will see that at 9:00 p.m. it is still quite light!
