I have 20 chicks that are ranging from 1 1/2- 3 weeks old. I put them out in. A corner of the run while I cleaned out their space in the coop. I went to bring them back in after 2 hours but they were having a ball scratching, running and dust bathing so I felt bad. They are In a corner of a covered secure run. They have food water, shade and dirt(Poured in a small pile for my bigger chick who loves to dust bathe and they all have spread to out already lol) It's 85 degrees outside with only a intermittent mild breeze. I had 1 pass away earlier this week so I know I'm being overly worried.
