I love reading about and looking at pictures of your animals too! Yes, just what in this world is truly "normal"? Some creatures simply have some greater needs than others, but when someone mentions "normal" in that manner, that's about like saying something is "perfect", as in there's no flaws of some kind. Everyone has flaws.
The word "normal" is misused and abused, that's what it is. I hope whomever said that about your chickens at least some sense not to say that about someone's child, though they may not view that as the same. It is the same thing as far as I'm concerned.
Someone once said something about my cousin when she was a baby. She was about five or sixth months old, healthy and beautiful, and this woman said to me (while the child's mother wasn't around), "Kinda big, ain't she?"
Like she was too big, and she was a little (though healthy) thing, really! I don't think I really said anything, I'm always caught off-guard about things like that; though this woman was a rather ignorant you-know-what, she also ran a local store, sold vegetables and such, I'm not sure what else since I never went in there as you could smell a stench from just outside the door. Mama said that Grandma said, "Don't ever go in there".
So consider the source, a lot of the time. The woman who said that about my cousin has since died.
In regard to animals, I don't believe anyone has ever said anything about any of ours that were less than "perfect". We had a beagle/hound/etc. mix who had a deformed front leg, but she was a dog that anybody could ever hope to have. Just as sweet, gentle, and easygoing as could be, but alert and protective when she needed to, not to mention she could still run, dig, and play with the best of them. We rescued her from the pound when she was a puppy, along with several other mixes. Some died with parvo, others we had to give away as there were too many (it was over ten that we took home
). She was the only one we kept and stayed with us for ten years until she died in 2005.
But yes, the "perfect" word would surely be "unique"!
