I have a little cochin chick that is 9? weeks old. It came with a pair of brown leghorns that are 3 weeks older as a gift for my son from the breeder. I posted when the female leghorn died of what the breeder thought was coccidiosis (sp). The cochin is still only the size of a coke can, and has been feathering for the last 2 weeks (finally), but is still only half feathered. My son named it Light, Light sneezes often and gets snot and bubbles sometimes too. Also gets a disappearing/reappearing air sac/bubble above the crop near the right wing joint. Otherwise seems happy and alert. My issue is now it's buddy (the brown leghorn roo at 12 weeks old) is way too big to keep bringing inside to sleep, as it has been getting below freezing at night for a while and baby still can't go out. Buddy stays in his own cop/run during the day and if the weather is nice I take the baby out, (they are separated from the rest of the flock), both are lonely when they are separate. Farmers say to cull, but I don't think it is diseased and will affect the rest of the flock. (I have to say it does look cute to see a rooster with a baby chick under it's wing) Am I wrong? What are my options for these two? The big guy can be integrated with the flock, but the little guy can't. I have pictures of Light taken two weeks ago, but I can't figure out how to post them here. I will keep trying and add them to the post later. Thanks edited to add photos. doesn't look very old does it? two weeks later it has teenage ugly feather syndrome.
