I have a chicken thats been doing it for weeks now. I thought it was a song they would do if an enemy or something was bothering them... but apparently its the egg song. I was listening on youtube and its exactly the long song thing that she makes. she's 17 weeks old. She's a buff orpington. it used to be the other one that would make the song and I thought it was a warning call or something that happened once or twice. she hasn't done it since... but lately "Butter" has been doing this song nearly every day. I've been keeping them in the run until 230 in the afternoon and then letting them out to run around. she's been doing her singing almost daily lately. I don't see eggs in the run or coop so I can't imagine she's laying any.. BUT, why the heck is she doing an egg song for if she's not laying eggs? what other reasons would they do the song for? do they sometimes do it as a distress call? Its probably mid morning when she's been singing lately.
