Ok I bought a coop online a few mths ago to give a home to our 4 Isa brown hens and that darn rooster LOL, after a few weeks when putting them away at night I see that there is not enough room, so after telling the wife they need a remodel!! , We went to home depot bought 7 sheets of 1/2x2x4 panels 8 cinder blocks , two 1/2 inch dowl rods and I have a 4ft x 10 storage unit door (the roof) So after a few hrs the coop is twice the size and last night we added a lean-to to protect the gals during the rain, so we put them away and I go check on them around 10pm and all 5 are huddled up in two of the 4 nesting boxes???? Why would they be doing this??? there roosting bar is 4ft long and there second story loft floor is 4x 3 and there is 4 nesting boxes???? could they just be afraid of the new HUGE coop??
