Well, my little duckling has died, so Ii think that there was more things wrong with her than just the niacin def. So I just have her little sister left. Just one duckling. I have moved her ( tilly ) to a hage three ply cardboard dog biscuit box. ( Trust me, It's huge) She does'nt have the heat on her anymore because I did the night I moved her to the box, and she had the heat on her, she was panting. Well, tilly is just about heartbroken as much as I am. She was honking at 2:30 in the morning, so I had to lay on the floor next to the box with my face close to the door I made in the box. She was so sad and confused. She put her beak through and layed it on my face all night. I feel bad for her so I'm focusing on getting her a new sister. the problem I'm having is (1) almost alll the stores don't sell anymore ducks for the year (2) if they do they arent sexed or the breed i want and (3) I want my money back for both of my ducks. I'm working on getting more now so that's under control. I want my money back because first off, I got the wrong breed of duck and because willow died within the warranty period. Tilly was supposed to be a cayuga but she is a khaki campbell, and the one who died ( willow ) an ancona, but was obviously a pekin. S o I am so mad at farm and fleet for giving me the wrong ducks and the ones i was supposed to get, probaly ended up going to someone who is just going to eat them. I can't believe it!! I f me and Tilly haven't suffered enough!! But I thank you for the advise and I'm still giving tilly the niacin anyway.Thank you for all the helpful tips you've given me since i joined BYC.
