While feeding my meat chicks (cornish cross), I just noticed one who is still naked! They are 3 weeks old and most of them are mostly feathered--tails, wings, back and chest mostly. This little one has 2-3 wing feathers and that's about it! Has anyone run into this before. While we are now entering another heat wave, we were much cooler last week. I am glad I decided to give them a heat lamp the last week as nights were cool. This chick would have been pretty cold.
