I started out with just normal chick starter. I haven't used layer until now. I am going to switch to organic soon but haven't yet.
I did do something to save money though. I started a fodder system which I will be switching them to over the next few weeks. I bought organic seed from azure standard. That plus a 20 dollar green house shelf from tractor supply. (They were on sale) so for less than 100 I have probably 3 months of feed. I'm 5 days in and i already have sprouted seeds.
