Hello! I'm rather new to raising ducklings and in need of some opinions/advice! For my Master's research, I'm hatching Blue-winged Teal eggs that came from wild nests and raising them in captivity to study and monitor their behavior. Right now I have 14 (8 that are in the pre-juvenile stage and 6 that hatched last weekend) and they are on Dumor Chick Starter/Grower feed. They seem to like it with no problems, but the bag is getting low and I have 13 more eggs soon to hatch. I was wondering if switching to the Purina Flock Raiser would be wise, or to stick with Dumor starter/grower and then switch to grower/finisher at 10 weeks. I know Dumor's protein decreases once I switched bags, whereas the Purina Flock Raiser would be at 20%. I am trying to monitor their migratory restlessness or any pre-migratory behavior, so perhaps more protein is better? But I was worried about a possibility of angel wing. Any suggestions/opinions would be greatly appreciated! Thanks so much!
