How to turn off the shuffle feature on my iPhone iPod?

No matter what I do, I can no longer skip to the following track. This happens when I tap the Skip button (>>|) and also when I double-click the clicker on my headset. I've rebooted and fiddled with the shuffle button on the top of the playlists. Tapping that button does exactly the same thing as clicking the skip button (>>|). Any ideas?

My iPhone 5c won't connect to iTunes?

My phone recently stopped working (it has vertical lines and the screen is unresponsive, so I can't manually restore it to factory settings) and my phone won't connect to itunes. My phone is charging, but it's not showing that it's connected. What do I do?

IPhone 6 storage problem? Says memory is full?

I have a 16gb iPhone 6 and earlier today I got a message saying that the storage on my phone is almost full. Under usage settings it says I have used 12GB of storage, however under storage management, the very few apps I use, and the pictures I have, only add up to about 1.5GB. I don't have any videos, I deleted all my safari history, and text messages, and it still says my storage is full. It even tells me that I have 0 bytes available. I know this is false, and it's making it so I can't take pictures, download apps, or even update to the latest iOS because it says I don't have enough space. Anyone know what is causing this, and how to fix it?

Why do a lot of farmers do this with chickens and ducks?

I notice on Youtube and in real life that if farmers have chickens, especially lots of them that roam, then they often will stick a small flock of turkeys in with them. And with ducks, I notice a lot of farmers will stick a few geese in with them.

Why is that?
