Is my tiny girl feathered enough to go outside? (Pic heavy)

 your temps at night are you able to add heat light to coop if they need it also maybe add a box with wood shavings they can lay in to also help keep in the heat. my girls are only 4 to 5 weeks and staying out this whole week but are lows are in the 70's i know have to worry about them over heating

I think they will be fine, If you are weary to do it, than add a heat lamp in one corner of the coop..... I would say they would definetly be fine if their were 6 of them to keep each other warm, but since theres not I think you should add a heat lamp at night....

I agree with highpointfarm - at 7 weeks, she should be good to go.  But the heat lamp's a good idea since there aren't several birds to keep each other warm.  I have 6 girls - about 9 weeks - in the coop, with night temps at mid 60s.  They do a great job of grouping together for warmth, but I have a heat lamp in there in case we get lower temps and heavier breezes w/rain - which is how we've been this past week.

You might also consider the box idea - gets the girls out of the chilly wind.

Good luck - have a great day, and God bless!

we just got a new coop. Most of my birds are 10 - 12 wks, but i have one thats only about 4.  The bottom of the coop is wire (not sure if i'm going to leave it that way or not) so i plan on having a box with bedding in for awhile and possibly a reg lightbulb over it if needed.

The weather here has been 85 some days/48+ those nights, but there are still days like today....41 and rainy/breezy with the nights around 35
