Jim, got it...Question about the heat lamps, yesterday I built a 8' X 4' pen and the extra space was truely needed for the 16. The ducks/ 4 embden geese are running around and flapping their wings and just enjoying it and the various sizes of birds is less of a issue for the smaller ducks. However, I moved the heat lamp up to about 18" above the floor resting on top the plywood enclosure along the end sides. At what point do I turn off the heat lamp. If I'm going to move the birds to the island at about 6-7 weeks and build a cage area with access to the lake's water and a built shelter to get them away from the weather and feeding, do I transition them cold turkey so to speak or should I continue to raise the heat lamp until 2' or more and into the 6 week period of time????? Once the birds are comfortable on the island in about 2 weeks (8-9 weeks old) I will take down the chicken wire fence and let them expand into the lake and hopefully have them return to the island nightly and for nesting....Thanks
