Got mine on May 25th. For 3 weeks they were inside with air cond. About 3 1/2 I moved them out to my little fenced area right out the back door in an ex pen with a top, early mornings til it got up to 90`. Brought them back in about 11am. Did that for about a week. Then along with that, started them outside about dusk thru the night, for a few days. Then moved them out for good about 5 wk with fan, ice blocks every 2 hr in afternoon, have a heavy rug on the west side that I keep wet with cold water, along with moving them out to bigger ex pen in very green shady area early morning and late evening. Lots of wet grass and water. I got 7 Buff Orp Pullets, and so far I still have all 7.
Still at the same routine and will be til Oct when I can put them in Hen House 24/7 to acclimate them to the yard and Hen House. Its gonna be a long hot 3 more months for me. NEVER again will I get chicks in the summer. From now on they will arrive in Mid to Late Sept. This is for the birds!! Its been over 100 here now for 35 days and no rain. We are toast in this country!
