I have a BO who is 5 weeks old and has almost all her feathers in (minus a few still coming in on the head). I also have 3 Production Reds, 1 EE and 1 Jersey Giant, they are 4 weeks old. They sleep in a 5' x 5' brooder box at night and 5' x 8' run during the day. They are all eating chick starter and have plenty of water. I found a large feather in the brooder today, I didn't think much about it since it was only one. When I checked on my chicks earlier there was another large feather and by the color of it, it belongs to my BO. A while later I found another one. All the feathers are light in color so I believe they are all from my BO. Is this normal? I know they replace their baby feathers but do they molt again while young or just when they turn 18 months? The feathers look perfectly normal and I can't find any injuries to her. I don't even know which feathers these are (tail, wing, etc.); I'm new to all this. I haven't seen anyone peeking her, she is top hen-to-be too, so the others pretty much do as she says.
