Hi everyone! I have recently started my "homestead" with six chicks and 5 ducklings. The chicks are about 3.5 weeks old, the ducklings are about 2.5 weeks old. I've noticed that I can see little pin feathers coming on their backs and butts, but just today I noticed that two of them are losing their fuzz on their neck and wings but not getting feathers yet? Is this normal? I'm feeding them starter feed (non medicated of course). I'm putting a picture too so you guys can see.
