I have three Muscovies, two females and a male - love them! This is my first run with ducks, so about what age will they stop growing? They will be 15 weeks on Thursday and they've seemed to stop for the most part. So are they done or just building up to a monster growth spurt to shock me!? Also, we've had our first glimpse of fall Although it will be back to blazing temps this week sometime, but do the Scovies seem to fair well in colder weather or do you take extra precautions to keep them toasty? I have heat lamps for both the Scovies and my hens when it really gets cold and of course will have the coop closed up at night, but should I worry about anything more than that for anyone? Thanks in advance!
