I have four chicks that are all 6.5 weeks old. We have two brahmas, one cochin and one golden buff. They have about 98% of their feathers and look like miniture versions of their adult selfs. They have outgrown their brooding box and are now living in a rabbit hutch in our house. This arrangement has worked very well but they are now starting to smell even though I clean their hutch out every day. We live in northern Ohio and the weather currently is mid 60's during the day and 40's at night. We have a nice chicken coop with a run and I'm wondering if it's okay to put them outside yet, with the brooding light set up inside of the coop.
