My Muscovy had 4 ducklings (out of 6 eggs)on Aug. 5th (See my Personal Picture). We let her take care of the babies and let her and them in and out of the pen at one week. All are doing great. Of Course the male started to mate with her after a few days out of the pen. Two nights ago(Sept. 10th) she started to sit on 9 eggs! I think this hatch will be better because she had an egg a day and then sat. The other 4 are doing great and now by themselves. Although Papa keeps them in line!
