My chicks are 3 weeks old and i have noticed 2 this week doing the whole throwing their heads back, looks like they are trying to talk. I havent seen it alot and they are both eating just fine. Am i being paranoid??? BTW - one is the one whose gender is up in the air... got a decent size crown for her age and has some wattles growing in.... (did i mentioned she is only 3 weeks old).
