Are there specific breed(s) of chicken that are known to be QUIETER then the rest? I ask because after removing the 2 known roos from my group I expected to have just peeping and quiet "regular" chicken noises ... NOT! Apparently one of the chickens (a pullet) has decided that she should take over the roos job every morning. So as soon as the lights come on for anywhere from 10-30 minutes ... SHE CROWS! I've also noticed that she sometimes does it if I am near them for a bit and then walk away (out of sight). Also, a couple times I noticed she did it and upon inspection of the area one of the cats had happened to walk by. The other pullet makes peeping noises but NEVER has crowed. Due to our situation we have to have "quiet" birds ... so sadly I fear I am going to have to get rid of ms. NOISY-BUTT ... which will leave me with another dilemma ... I know they like to be in a group, so I need to find her a new friend or 2 that will be as nice and calm and quiet as she is. Any suggestions?
