I have read, that drakes will try to breed even chickens. Time will tell, if things get out of hand for the females, she has a decision to make. I would prefer a 3 or 4 female to 1 drake myself. Again this is what I read. They don't pair up like geese, and a lot of other animals, including hawks and eagles.
If need be I will try again next spring and go from there. It's not fair to separate them since they do everything as one, it's like watching little soldiers. Not to mention the extra space and maintenance. I will let her decide and give her my input, She will be heart broke, but that's part of doing this. She said "I will help you with everything to do with the rabbits and quail", I said we will see. Sure enough, she can't butcher. Cried, but stayed out there. Now I have an extra butchers apron. I told her it was fine, and I expected that already.
