I truely hope you contact and visit a letgitimate pheasant propagator to get good information to raise pheasants. It is more than just hatching eggs or buying chicks and if not done properly you will just waste your time and money. Do not bother covering the ground with chicken wire because it will stop nothing from entering your pen. You will need to have your pen sides burried in the ground anywhere from 12 to 20 inches to keep predators from digging into the pen. Additionally, if you are going to have tall native grasses in the pen, additional cover such as brush piles are not necessary. There is a lot to know in order to raise your birds to release age and have enough of them survive to get the most for your money. They can start to fly already at 2 weeks of age for short distances. They should not be left outside in a hardening pen for more than 8 to 10 hours until they are at least 8 weeks old because they will not be fully feathered until then. There is too much you should know to get it from a message board. A message board is not the place to get the best information to do what you want to do, you will get information, but not all will be correct or the best way to proceed. Go to the PGC or a licensed pheasant propagator and pick their brains and take notes, to give you the best succes possible. It will cost a little more to do it right, but you will like the end result better. Good luck.
