They get starter grower with layer. They're aged from about a year old to best guess about a month old. We called our chicken lady we were buying from and she recommended getting Tylan and starting injections of 1/2cc for juvenile and 1cc for the adults and I called around and finally found someone that carried it 3 mins before they closed so I paid over the phone and they left the bag in front of the store for me. The chicken in the video that was sneezing got an I junction last night and she seems right as rain today. Their poops are all solid and normal color and they're all eating fine. We've already made the only water available dosed so we know they're getting it. That's what has had us baffled they seem fine then the next morning when we go to let them out were finding one dead just about everyday for the past week. Aside from it being heartbreaking because they're our pets not food it's getting very expensive because the ones that seem to be dying off on us are our expensive birds like the different Polish, red laced blue wyandotte and our chocolate cuckoo maran. Our chicken lady told us a lot of people are having problems right now bc it's been in the 90s and raining everyday so the ground is staying wet and we need to get them off the ground until they get over it so we went and bought a truckload of lumber and rolls of wire to make pens that are off the ground and so we can seperate them by like kinds.
