I vaguely remember something about @Lacrystol losing hers but can't remember the details. I was thinking it was a predator attack or illness or something like that.
And yes, I should have asked the OP about conditions at her place. Sometimes, especially when I'm short of time, I mistakenly assume conditions are the same as ours and that the Calls are out of their pens only when they have at least some amount of supervision. I'd certainly never recommend they be left out while the owners are at work or even at the grocery store for a short time. I don't let ours out during the day even though I work from home because it's far too common for me to get caught up in a crisis at work where I can't at least check on them frequently. Ours are out of their pens on weeknights after the hubby gets home and all day on the weekends and holidays.
NOPE, didn't loose the from disease or illness, NOPE didn't loose them from predator,
Well let me take that back. We did have a Fox issue and the fox would sneak up to them, grab them by the neck and take them away. I remember chasing one of those Butt heads down.
If it wasn't for the ability for them to Fly off, a fox would have gotten a lot more then what they had gotten.
I did have a group fly off, Not sure why, it was a group of 10 call ducks, I was sooo Devasted, Not sure what caused it because in that group was my favorite Chocolate bibbed named Sassy. OH she was sooo talkative..
But the odd part was, I had all the ducks trained, kind of, whenever a predator came into the yard, ALL 27 at that time, would FLY up to the house. Imagine That many calls, with there LOUD VOICES, it was VERY easy to determine what was going on...
But This ONE sneaky fox would sneak up and grab them very quickly and take off, Needless to say, That fox is NO longer an issue. I believe he had something wrong with him because he had missing hair and is no longer with us. THANK GOD, as sad as that may sound. He was also covered with ticks and fleas and VERY VERY skinny even though he had gotten a couple of my ducks in the past.....
Calls do not usually fly off in the winter, Speaking on my EXPERIENCE ONLY, they aren't big fans of the cold. I have noticed when I let mine out they will lay in the snow and not move, Very easy to pick them right up and examine them or just to hold them.. I don't believe they have the skills or capability to fly in harsh weather at least I have never seen mine do it and again I'm speaking of what I have observed... They Usually stay CLOSE to home.
Here's my percentage breakdown of flight reasons:
5% - to fly from one end of the yard to the other
10% to escape from Predators - CATS, FOXs, Raccoons ETC..
85% to escape from a Male.
I have noticed that the Female will Fly First to get away from the Males, but right behind her are the boys. They never go far and will always end up close to a safe and a secure but CHALLENGING spot so that the boys will leave them alone..
If you have a way to secure them GREAT, it's the best thing if your going to let them free Range, in my opinion it's best to leave the wings..
