I was at the local shelter and a woman was surrendering two black maran chicks. They are supposed to be 2 weeks old. I got my birds free as adults so know zilch about chicks. They are still downy except their wings. My friend who is at work and cant get a look at them now thinks they are older if they have feathered wings. They seem to have A LOT of feathers on their legs compared to the rest of their bodies. Any thoughts on if they can go outside or need indoor time? Its has been in the 40's overnight last two nights. Also searched for pics of chicks at specific ages and didn't see anything that matched. Downy but with wing feathers=what age? thanks
