Hi everyone ... I have 2 Pekin ducklings that are about a month old. I got them 2 weeks ago and am enjoying every day with them. This board is literally my bible for learning and I'm so appreciative for that. I've been reading old posts and have a few questions and was wondering if anyone could offer any answers, that would be great! When do I stop feeding the ducklings their crumble. They are currently on Purina Start and Grow. I got my ducklings from a local farmer and it was hit or miss if I have a boy or a girl. One of the ducklings is a bit larger than the other and his/her bill is bright yellow, the other boy/girl from day one had a pinkish bill and is smaller. I named this one Rosie because of the rosy, pinkish bill. I just googled somewhere and they said this could be an indication that this is a female. How soon can you you tell if you have a Drake? Both have raspy quacks, I know I'm shooting in the dark here. Lastly, I do have 7 hens and a rooster and have heard that you can't feed ducks chicken feed, mine get layer pellets and scratch. Since my ducks will be free roaming with the hens and rooster, what happens if they get in the chickens feed? Last question, it's about 50s overnight and high 60s low 70s here during the day, when can I turn off their lamp? I have been keeping it off during the day. Thank you so much for passing along your knowledge to me!!!!
