what part of 29th dont you understand??
Not 28th its starting on the 29th bro read the announcement a bit carefully
The Wiki article about the Easter Event originally said, 'On 27th March, all of the players will be entrusted with a special chicken'. This was, at some point, corrected and changed to the 29th March. Therefore, I don't believe adronicus misunderstood what he originally read and was correct in expecting to have a hen!
In that case (as long as your very active) its worth while to get the second chicken as that's an extra 12 per hour, 288 per day, 2016 for the week
therefore 200 gold for 15 CP and 3 heightened senses
It certainly appears a good deal. Yet, I think it is structured to favour those who can spend very long periods online (like you mention), a bit like farming every five minutes. After all, you can feed your chucks in 5/ 20/ 60 or 120 minute intervals and I am sure the five minute option will yield better rewards than the two hour mark.
The Wiki article says, 'There is no guarantee that your citizens will bring back food, but as long as you keep searching, you will find enough to keep that chicken happy'. If there is 'no guarantee' of finding food, just how long and hard do you have to search for?
If you can't spend a lot of of time feeding your chucks then, to buy, a culture point becomes expensive, 1 CP = 150 eggs = 150 gold. You can hold three Olympics for that, but of course, the downside of the Olympics is the time it takes to hold. Here, you can buy instantaneous culture points, with no waiting required!
