Yes, they grow super fast! I hope they're OK in their cage. My dog is really interested in ducks, too. I've been merciful to him and let him come to the coop with me, but if he sticks his nose in, that's a different story!It's been a day of struggling . We tried to build another cage in backyard it's so expensive . It only took for the 5 ducks and 4 birds we still have to make improvements to it. It's hard to see it was dark.hope they servive the night . It is going to be a chore keeping my dogs away from it without scaring them to much tell I can get boards and other things around it for there privacy issues. When they start laying there eggs in a little while there teenagers or pre teens . They grow up fast,
