I've began looking at food for the coming chicks, and I have a headache.
So, for the first ten days we have starter first age. However unlike the recommendation I see here it's around 12 % protein. I'll do with that and I expect my partner will add the mixture of boiled egg and bread the first days.
( BTW I think one of the main problem, beside salt, with today's bread is the leavening agent, most of the time baking yeast instead of sourdough. I'll make sure we get sourdough bread).
Then, I find an other type of food called either second age, or pullets/cockerels. Now depending on the brand it ranges from 12 % to 21% ( that last one is professional range). That's a huge gap and most of the brands that are easy to find are rather on the low spectrum.
I would like and will have to integrate the little ones as soon as possible with the actual flock, hopefully between two and three weeks. That is, if we don't have too much aggression seen how they all absolutely hate broody Chipie. So this means the same food for everyone. Now I understand layer food with 3 to 4 percent calcium would be harmful for growing pullets and cockerels. Should I put everyone on this second age feed thing and try to find one with higher protein content ? Or go with "all flock", that in my country has about 14 % protein ? Or do a mix of layer and all flock ?
I'm sure anyone who read up to this point also has a headache by now
