If your moving her to the garage I'd keep her with a heat lamp till she is completely feathered. highs during the day sound good but 50's at night might be too low with out heat. just give her room enough where she can get out from under it if she gets to warm, at night. I'd say a couple more weeks getting use to change from house to garage then out of doors should do it. Have ya'll started her coop and run yet?Scuba's box smells horrendous. We are going to put her in the garage today since it is finally warming up outside. The average temperature for this week is supposed to be high of 75 low of 54. We've had her for 5 weeks now...not sure how old she was when we got her but we're assuming 3-4 days old. How much longer does she need her brooding lamp? She almost has all of her feathers in. Just missing the ones on her spine.
