I picked up my first seven chicks this last weekend. (13 more this Wednesday). Tonight I noticed that one of them chirps much louder than the others. It is a White Leghorn. The other six are other breeds. Are White Leghorns louder than most other breeds? Or is this a sign of potentially being a roo? By loud I mean the volume. It is not chirping any more than the others. They are all quiet at night. They only chirp during the day when they are active. They are one week old. Thoughts? Thanks.
