My 3 silver Wyandottes are at week 15. Do I stat transitioning them from starter to layer feed now? Soon? Maybe start with 75% starter/25% layer for a week, then 50/50 for a week and so on? I realize I am probably being over-precise, but all those years of teaching math and science have left me hopelessly obsessed with exact measurements. TIA for your patient help.
I waited to switch feeds till they started to squat when you reach down to them and combs were red and swollen on some of the pullets.
I started to switch feeds by mixing Layers pellets with Start & Grow crumbles 50/50.
I offered Oyster Shells in a separate container.
I also mixed the pellets with Scratch Grains 50/50 and scattered on the ground to get them used to pellets. You can skip that if you're switching to Layer Crumbles.
I did that for about 2 weeks until the Chick feed ran out, before adding just Layers feed, to the feeder.
You can offer Oyster Shells separately at 16 weeks.
I would keep them on a Non-Medicated 18-20% Starter-Grower feed till they squat or the first egg before switching.
My Red sex-links started to squat and Combs were swollen and red around 15 weeks so I started the switch at 16 weeks and 2 started to lay at 16 1/2 weeks and the last to lay was 19 weeks.
My hens are now 28 months old and I am feeding them a Non-Medicated 18% Start & Grow with Oyster Shells separately. Why?
My hens feather pick on a 16% layers feed, they don't with a 18% Protein feed. GC
