i have been wanting to add ducks to my flock and decided to do so this year and thought calls might be good since their small....just have a couple questions about them. was reading the stickies and it said that calls are loud and talkative...have no problems with talkative as my 5 LF cochin girls are pretty talkative but how loud are they? are they hard to hatch out? couple listing on ebay have said that they can be difficult and getting hatching eggs is the only way for me to get calls. what would i have to do to help them hatch well? would a drake and 4 girls be ok or would a drake and 5 girls be better? are they decently friendly? i spend a good amount of time with all my birds so if time is needed fo them to be friendly i've got it are they flyers? if so does that mean i have to clip wings so they stay at my place?
