I'm getting 10 ducklings next week. Unfortunately 9 out of 10 from our last batch were killed in a night time raid at 3 weeks old (cat? raccoon?). Our 10th is ill, and I don't want to put our new ducklings in the pen she was in for fear of contamination. It also turned out to be a bit too big for ducklings (~4ftX4ft). I have seen people use plastic bins and cardboard boxes for a few ducklings. My question is, what is the ideal size for 10 ducklings? Something that is big enough that they can use until they're ready to go into the duck run (3-4 weeks). They'll be outside, with a lamp primarily for night time (we're still in the mid 80's to 90's during the day here). I prefer to use hay straw as a bedding. I'll post pics when they arrive!
