The chick invasion of the goathouse

All my chickens are able to get into the goat paddock but it seems that it is the group of 5 chicks (the ones aged just under 2 months) that have made themselves most at home there. Though they roost in their own henhouse, they have also taken to sleeping comfortably through the day in the goathouse. This may have something to do with the supply of food. The goats' feed trough is in the goathouse and when I put in the feed, the hens are often ahead of the goats when it comes to having their fill of food.
