Switching to Layer Pellets/Crumbles

It is about that time that I switch my chickies to big girl feed. They are coming up on 18 weeks already!

Firstly, I didn't know I needed to choose between pellets and crumbles. The best thing I read was that the crumbles are easier to break down and digest than pellets. That being said, I assume that the pellets are less messy than the crumbles. I don't think it really matters, but for funzies, I'm going to buy the Purina Layena Pellets and the Crumbles and see which one disappears first.

Note: there is also a mash option that is almost like powder which seems really annoying so I didn't even put it into consideration really.

I read that, 

"As stated, crumbles and pellets are essentially the same thing presented in different forms. Whether in crumble or pellet form, chicken feed is typically a mixture of grains, protein, vitamins and minerals. Both types provide the same level of nutrients to your brood — dependent, of course, on the quality of your feed and whether you’ve opted for organic. The key differences you’ll discover are:

• Texture: Crumble is a coarse, loose texture that is typically easy to eat thanks to its soft consistency. Pellets are compact cylinders that hold their shape nicely, making them easy to store and serve.
• Manufacturing: As we’ll explore below, crumble and pellets are processed using different machines — a crumbler or a pelletizing machine.
• Convenience: While both pellets and crumble are popular options, they’re convenient in different ways. Pellets are the most widely-used and easy to find chicken feed option, making them more convenient for farmers. They also ensure consistent nutrition in every bite, since all of the pellets are the same size! Lastly, they offer low mess and minimal waste. Crumble, on the other hand, seems to be the easiest to eat, making it a convenient option for a quick feed and for birds that are particularly young or senior in age."
