Ok, I have a 6 week old chick, a Bantam Cochin mixed with, I believe it's Bantam Buff Orpington, and my Silkie hen hatched the chick out in the coop. When the hen was getting bullied a little too much for my liking (by overly amorous boys), I brought her and her chick inside. They've been inside ever since because the chick is not growing fast at all, and after 6 weeks all the feathers it has are the ones on it's wings. So maybe 4 to 6 feathers total. When the chick breathes, you can hear a clicking noise, and on occasion we've seen bubbles coming out of it's mouth, nose AND eyes after it has drank. It peeps like mad, is super friendly, and loves to snuggle. It's eating and drinking good. I can't put it out in the coop, it's cold now, and the chick gets so cold so easy. Can anyone tell me what could be causing these symptoms. I've read about a lot of problems in chicks, and I suspect that there is a hole between the esophagus and trachea, and that it gets liquid in it's lungs when it drinks too much too fast. This chick likes to stuff it's crop til it can barely stand up. Could this be a genetic defect? I see no mucus discharge, so I don't think it's a cold. What chances does this chick have? It's so sweet, I don't want to lose it, but it always seems like the super sweet ones are just not meant to be here for very long. Any advice would be much appreciated. Thanks.
