Hello I'm brand new to this site and this is my first year owning runners. I bought a penciled, gray and white as ducklings bout 6 months ago. I was unsure of the sex of them and thought the gray was drake and other two were females as my gray has a very quiet, muffled quack and the others are very "talky", Well i just read about the curly tail which all 3 possess. So first question is there's no way they can be female and have curly tail right? which leads into my second question, my runners are my lil babies and will follow me round the yard and my penciled and white have always eaten out of my hand, my gray will come close but only (I believe) cuz his "girls" are by me. The point is at least for the 2 is that they seemed pretty people-friendly and I considered them tame. They last couple weeks their behavior has changed. For my wary gray guy he will run up to me when I hold out treats for them, and ignoring the treats will proceed to attack my fingers and hand, he went from shy to aggressive and my first thought was--his girls are gonna start laying and he's getting protective of them, which confuses me when i found out about the tail-curls. My white runner is the only one that acts "normal" but my penciled started acting really weird too. He/She always followed me around but now when i walk he will jump at my legs, stand on my skirt, stand on top of my feet as if to prevent me from walking, he/she doesn't bite me like the gray one does, and when i stand still he'll be calm, as soon as i start walking he flips out, quacking and jumping on me. Has anyone dealt with this behavior before? Is it a territorial thing? Is she just really excited to see me? (They run up to my car when i pull in driveway) Oh yeah and they've always stayed just at arms length when they come to snack outta my hand but since they've been so bold and weird lately i can just reach down and pick em up, no prob. I had cayuga ducks last year and they never acted like this.
