slow transition?

[peartreehens]

My chickies are about 8 wks old, and so are ready to go from chick mash to grower (pellets/crumbles/whatever). My question is this: do I need to mix the two for a while to make a slow transition? Or just swap it straight across?

also, several brands of grower available in our area, how to choose? thanks!

If you have starter left, mix them. If not it won't hurt to just switch.
I like a pellet if you can get it in a grower for less waste.
Read the ingredient list. Most are primarily corn and soybeans. Soy boosts the protein but if you can find something with fish or pork meal go for that. Being omnivores they benefit from animal protein sources.
Stay away from anything that uses feathers for some of the protein.
