I hope someone can help. I have eight, 7 week old BLRW chicks in my brooder. Yesterday I bought a new feeder and started them on poultry grower feed as suggested by the feed store. Also, seeing as how they have all of their feathers in, I figured it would be okay to remove the heat lamp (red bulb), so I went ahead and did just that. This morning when I went downstairs to check them, everyone/everything was perfectly fine. This afternoon they were also fine, but this evening when I went down to check on them I noticed one of them had some wet looking back feathers. I picked him/her up to have a closer look and saw that a large patch of feathers above and under the wing have been plucked out clean! Why would this happen?! Are they just getting too overcrowded in their brooder (large kiddie pool) and are starting to get stressed out? Could the removal of the heat lamp be a problem too?? I just find it odd that this would happen so suddenly.
