I have 6 chickens, 4 buff orps sold as hens (I forget the terminology) and 2 silkies sold as straight run. The 4 BO have been what I woul consider challenging each other, chest bumping and ruffling up their neck feathers etc. are these just hens working out their peckin order or does it sound like I might have some roosters amongst us? Also they peep like chicks do until today one started to sound like it was straining to cluck. Again maybe they're just going through puberty and findin their voice or maybe it was the beginning of a crow?!? I got them over memorial day wkd and they were about a month old at the time so they are 3-4 months old I'm guesstimating. Thanks!
