I am new to this chicken stuff but as I was playing with my 18 day old chicks today I though, wouldn't be great to have a portable chicken run! I want them to have fresh greens and grubs available to them, and I was afraid that if I built them a permanent run then they wouldn't always have the greens and grubs. My solution that I thought up was a portable chicken run, like a chicken tractor but with out the coop part. I would place a roost in it so they could have some entertainment. But would I need to put a nest box in for four hens? They would only be in the run during the day and in their coop at night. They would have a nesting box in their coop, but once they are in the run, they can't go back into the coop. Do hens lay eggs during the day, at night, or both? Do I need a nesting box? Since we live in the rainy Pacific Northwest, I would have a something solid covering at least half of the top of the run. Probably part of a couple of the sides to. I would also have food and water in the run, but I don't want the food to get wet. Do you have any suggestions about what material for the roof and what material for the sides? The chickens would only be in the run during the day, and in their safe from predators coop during the night. Does the run need to be a certain size for them? It doesn't have to be high because I want to keep the weight down but I want a door that I can go in, I don't have to stand up straight once inside, and the chickens can go in (they can use the same door). Does this seem like a good idea? Do you have any ideas, suggestions, or comments? I would love to know. If anyone has any pictures of something like this that would be greatly appreciated! Thank you!
