16 weeks is the best time to switch the girls over, but I have found that I have to switch them gradually.
I begin at week 14 to mix a little bit of layer feed into the little ones crumbles. For the first week, it's just a few layer pellets in a lot of crumble. In week 15, I increase the percentage of layer pellets to about 20% or so. Then in week 16, I increase it to 50% layer pellets, 50% baby crumbles. Later in week 16, I increase that to about 75% layer pellets. At week 17, I'm up to 90% layer pellets, then up to 100% layer pellets.
So basically, I transition them over about a three week period.
The method works just fine.
