Were you ever able to get them to get along? I have 5 ducks that are 8 weeks old, 3 chicks who are 4 weeks, and new chicks hatching, and a friend just called and begged me to take 5 adult hens and a rooster, I am worried about them all getting along, the ducks and older hens/rooster and going to be introduced on friday, I am thinking of letting the ducks free range and putting the hens/rooster in the run so they can see each other before putting them in but not sure how this will go!
Thank you, I couldn't find the Velcro fabric, but sewed a 1.25" tube of flannel and applied the Velcro tape as you showed. I will try it on our handsome fellow tomorrow, he is just now starting with the gargling crow. I'm hoping this works. Though I wouldn't mind the crowing, but he has to fly under the radar here.
