New chicken keeper here and head-over-heels for beards, boots, and Easter eggers. Also like landraces & hardy dual purpose birds. What are my options?
I’m thinking about adding a Mille Fleur D’Uccle to my flock but how small are they exactly? My Americauna is small but would he be too big for a MFD? Is there another breed similar to MFD but larger?
I wouldn't worry about his size compared to theirs. I had the same concern with my big Orpington and some smaller hens, it looked really awkward at first but he learned to balance and finally get the job done. As long as yours has the nice rooster traits - tidbitting (calling girls for treats) and the girls are willing then it should be fine. If a larger rooster is too rough he could do a lot of damage to small hens.
He should work to make EE's with boots and beard/muffs.
The only dual purpose breed I know of with Muffs and Beards are Faverolles. Crossing Faverolles and Ameraucana is done often enough that people named the mix Favaucana.
