I'm a week out from receiving my ducklings and don't have local access too starter feed. Local shop has plenty of unmedicated 16% growers but no starter in stock. Will this do? I could always order some starter online and have plenty of time for that but after reading up it seems like they will only need it for the first 2-3 weeks anyways. Can I make growers work if I wet it down or grind it a little smaller as dry? Is that even needed? Thanks in advance!
