I know there's plenty of talk about how& when& what to feed your chickens. But I'm still a little confused& not sure if I'm feeding them right, so I want to double check& make sure. I know you guys on BYC r very helpful. So... I have 19 chickens. 3 which r Roos. 16 hens. I have RIRs, Buff Orpingtons& Blue Andalusians. They r all 24 weeks old. I started feeding them all layer crumbles at about 18 weeks or so. I get a 50lb bag of feed about very two weeks. I have a 5 gal bucket feeder which I fill up about once a week. They haven't started laying yet, but from what I read, some people have had these breeds lay as late as 28 wks. I don't give them grit as I've read they don't really need it bc I'm feeding them crumbles. I don't feed oyster shells on the side either bc again, I read that they only need them if I'm feeding an all flock feed. Which I'm not, I give them Layer Crumbles. So basically, am I giving them the right feed& in the right amount? Do I need to give them oyster shells on the side? Do I need to give them grit? I just want to know that I'm doing my best to keep my feathery friends healthy& happy.
