We had a breeding pair of Pekin Ducks. They were housed with the chickens for about 8 months until it seemed to not work when the Chickens bothered Dafney while setting on her nest. So I built the 2 ducks (Dafney and Donald) their own pen. It is a woven wire pen covers snuggly with 1/4" chicken wire at about 4ft tall. The pen is about 20' x15' in size. However 3 weeks after Dafney began to set on another clutch of eggs something began to raid her nest, stealing eggs and taking newly hatched babies. One morning while feeding and watering I decided to wrap her duck box in chicken wire to protect her and the babies. Two days later I found her with only one baby duck and it was near the end of her time to hatch any more eggs. We decided to bring the baby into the house to keep it safe. there were 4 eggs left in the nest. Over the next few days she quit sitting and the eggs were all gone but one. I left the egg because she does not like me in her duck box especially after i stole her baby. A couple days ago my son goes out to feed the ducks and discovers Dafney half eaten in the corner of the pen. He was devistated they are actually his ducks. So I put Donald in a rabbit hutch and set traps all around the duck pen and Dafney's remains. the next morning all the traps were sprung but empty. The rest of Dafney was eaten. We are not willing to put Donald back unprotected nor our 2 week old baby Curly duck. So as this is our first time raising ducks I am looking for help. What type of pen do we need to use and how can I make this pen safe for my son's ducks? We really enjoy having the ducks and love to watch them splash in their pool. Curly thinks he is a person I don't thing he knows he is a duck and as much fun as it is having a duck in the house he is growing up fast and will have to go outside pretty soon. I don't want to see my son greive like that again and I feel like I let him down by not building a better pen the first time. Can anyone give me the info I need to have happy, healthy, and safe ducks.
