My chicks have very ruffled and ugly feathers. I’m thinking it could be a sun deficiency because here in las vegas, it is 100+ degrees about every day so I didn’t take them outside until they were two weeks old. I took them outside because I noticed their feathers were starting to get ugly. They are now 4 weeks old and their feathers are still ruffled and ugly. They’ve been outside every day all day for two weeks. Is this a sun deficiency? How long until their feathers start recovering?
