Our chicks are 10 & 12 weeks old and we are looking to move them into the coop at night which will mean they have access to the older (2 yr old) chickens feeders. Looking for advice based on their age. we are getting 2 more bags of the chick starter food to last the next two weeks and hope to move them in 2 weeks and need to figure out what to order from IFA. Not sure if I should keep the, all on chick starter a little longer Or change to the poultry grower option. They will be 12 & 14 weeks at that point. thanks for the input!
