Have researched my hind end off but have read so much conflicting information on when bob chicks can be put outside. We have approx 150 5 wk old chicks that we got from hatchery today. He had them in a broader room @75° and it was extremely humid. Our weather is currently 30° day 10-15° night but is supposed to be 60° by the weekend. We have a shed that will maintain 60-70° with 2 heat lamps. When can we safely put them outside.
