I read the post by Resolution about feed, protein, quality scratch & premium seed, Mazuri products and forage cakes. I know he is involved with either Mazuri or C&S but the reasoning to use a better quality feed for better eggs/embryo development makes perfect sense.
The Mazuri gamebird starter & feed is $18-$20 a 50lb bag. Purina is $15. The forage cakes are full of vitamins, so why not get someone to order them for you. Why feed 18%-20% protein to a hen we want to be in top breeding condition?
You are not the 1st to mention the lavenders and porcelains are a little harder to hatch. I'm wondering if they do not need a little more humidity during the incubation. I had 4 that didn't hatch, I'm sure they were all porcelains
.
I was running at 26%-40% + 98.8 degrees. 59% at lockdown. 9 hatched, 4 did not. I hand turned 9 times a day week 1, 7 times a day week 2 and 3 times daily after that.
I'm feeding Purina gamebird starter (30%) right now, waiting for my 1st bag of Mazuri to come in. I'm still trying to get someone who carries C&S products to order forage cakes. I have 4 perfect lavenders, 3 porcelains, and numerous splits to work with.
Hopefully, I'll be working on the insides as well as the outsides.
