Honestly... Silkies are too broody to eat layer... switch them over to 20% protein flock raiser or an unmedicated chick starter asap with OS on the side for active layers...
Both feeds are higher in
amino acids while not having the added calcium of "layer" that birds not in lay such as broody's, chick, roosters, molters, etc... don't need and fed
long term *could* (doesn't mean will) even cause gout, kidney failure, or sudden death.
Some Silkies seem to have a higher nutrient need
or less of an ability to absorb certain nutrients... especially if at any point they had to be treated for coccidiosis. Again this stated after I bred them for several years.
Using flock raiser or starter will NOT negatively impact your egg laying and might even improve it, will definitely improve the available nutrients inside your eggs... 22% protein was shown to give the best hatch rates (which to me says more nutrients my family is consuming when eating eggs), while 16% protein in most "layer" feeds is the MINIMUM needed to keep a light bodied bird in laying condition. Despite Silkies being bantam... I have put enough of them on the table that I would NOT call them light bodied. In addition to all things stated my birds have softer molts and recover sooner since I NEVER use layer after learning the difference.
I'm in disagreement... but we all have to face our own trials and errors.
