How soon can I put ducklings in the outside pen? Right now they are in the house under a heat lamp, and I'm managing the mess ok, but they are running out of water (with 2 of the bottle types) in between I leave for work at 6:30am & return for lunch at noon. Same in the afternoon & overnight. I purchased a larger (2gal) self waterer, but can't get it in the cage w/o it spilling everywhere. I guess the seal breaks when I move it. It will be great for outside tho. They are about a 8 days old. Temps here in NC are averging in the 60's but 30s to 40s at night. I imagine they need to stay in a bit longer...but should I try to only offer food in the am, lunch, and pm when I am here to be able to refill the waterer?
