I have 17 chickens now about 3 months old (15 are Speckled Sussex, 1 BO and 1 Australorp). I the last week or two, every time I go to to check on them, I see that they are mostly staying in the 10x12 coop. I have a 35 foot long run behind the coop, so they've got plenty of room to run and play, but they seem to staying in there. For example, today I went out to feed them a plum as a treat. After they feasted on it, they all happily went back into the coop to hang out. The coop and run are in dappled shade in a cool area of the yard. Food and water are outside in the covered part of the run. Anyone else experience their chickens happily staying in the coop during the day? When I come to visit they all shoot out the pop hole.
