You have 10 chickens as pets.
You opened their coop in the morning and 9 came out. You looked inside but the remaining one is not dead. The 9 outside were eating their food but you noticed one of them had blue legs.
You thought it had become dirty and so it was not a big deal.
The next day, when you opened their coop, again 1 did not come out for food and 3 of the feeding chickens were eaten by the cat outside the coop.
The very next day, when you were away, 5 of your chickens were eaten by the cat while inside their coop.
So can you explain, why did the cat only eat 5 chickens in the end?
Hint: There is more than one conclusion to the story. so, you have to figure out what happened to the chicken.
Hint2: Blue legs is also a sign of disease in chickens
