our's are about 5-6 weeks old and have been in the coop just fine. we don't have roosts in there yet though and i'm wondering if my husband needs to get that going soon. also, how high should they be off the ground? and do you all suggest a droppings shelf of some sort? we have 8 chickens in an 8 x 10 coop....i will be free ranging 2 or 3 per day until we can get a good run/outdoor space set up for them... tia!!
