Have raised a few batches using hoop-house style pens but decided to make two 8x10 Salatinesque pens for the 75 Cornish Xs this year. I found a how-to on Youtube and followed precisely. We're on week 4.5 and are seeing broken legs. 4 to date. I finished one and figured I had some time before finishing the 2nd. Almost done... So, there's 75 in one 8x10 pen. They're still pretty small, but they're laying down some serious fertilizer... So, for those that have built them, the first question is the horizontal tension wire; its a huge trip hazard/obstacle as its about 1.5" off the ground. Understand it lends some structural integrity, but is it necessary? Figure that may be a cause of leg injuries? Second is moving the pens. I ran over one before deciding to do a dolly. Grabbed a drum dolly and it lifts the back about 3". Invariably, 80% of the chicks take off out the back while moving it. Pretty frustrating trying to wrangle all those buggers back up. Third is feeders/feeding- we're not on the farm full-time yet so are only making one trip up there a day. The feeder is empty and when its refilled, they go gangbusters stepping all over each other to get to the feed. Appreciate any feedback- Thanks.
