They aren't game hen size yet, I got them less than 2 weeks ago. I put some cardboard up on top and against the sunny sides of their fence to provide more shade today, hope it helps. Their shade structure is absolutely hideous looking, though!
There is no way I am going to let them out of their pen, they are in a temporary fence in my garden. I can move their entire run, but have limited spaces to put them. They have to stay in the fenced garden area because of the puppy and most of the space is taken by plants right now.
I'm looking at moving the entire garden fence out a bit so they have a bigger place to roam but it will not solve the shade problem at all. The whole yard gets full sun. There are city setback requirements that dictate I can't put them in shadier parts of the property...which is so stupid. Because of the size and shape of my property, the only place they can legally go is smack in the middle of my front yard, lol
