How old are these birds? They sound like teenagers, which if that's the case, they'll settle down once they reach point of lay and hormones calm down.
I’m having a similar issue with my first flock of 4 - they’re almost 17 weeks old now, and I’ve had them for just under a month, and I feel that they were a lot tamer and more relaxed around me the first 2.5 weeks or so, and have recently and suddenly become skittish and shy. They would come running for treats and would follow me around initially to the point where they were underfoot all the time, but lately they’re super skittish and will only reluctantly come over for treats.
We had an attempted goshawk attack this week (I was with them, and I scared it off as it swooped from amongst the trees) and I have also been doing some gardening near their run - they didn’t seem too bothered by it at the time, but maybe the change has freaked them out? One bird also had one wing clipped last week, but I did this at night once they had gone to sleep and were calm, and it was quick and easy, no real fuss - she came to me and would eat from my hand the next day (watching her figure out that her flying days were over was pretty hilarious, poor girl!

)
They have never been afraid of me approaching the run but lately they seem to get panicky as I approach until they realize it’s me, and then they calm down again, but they still aren’t eager to interact or to come out and forage, like they used to be.
I would appreciate any advice on how to get them tame and relaxed again. Our Minorca (Tilly, the one who got a wing clipped because she almost got over our 7ft fence) has always been a bit skittish and not fond of being handled, but two of the others (who are EE mutts) would actually come sit in my lap for treats and snuggles before this.
Are they just being crazy teenagers? I’m trying not to take it personally

but I miss them being sweet and cuddly!
