My chickens have a habit; just wondering if it is normal. They take things that they like and hide it in their pen . My barred rock hen (Patience) found a big red shiny button in our yard and put it in her nest...she acted quite proud of it too . They find whatever is around in our yard (especailly things that are shiny), whatever they like and i find it in their coop. I have found little metal bits, buttons and lately...my cell phone (it's flat and small)! They were all sleeping on it as i was going crazy trying to find it. They took my cell phone!
