I always find the softly, softly approach best for the first couple of weeks when you have so many. Any grabbing of a passing bird creates consternation amongst the others and delays their taming."Meet me in front of the shed in 10 mins......"
If they're close enough for a stroke, such as when I'm putting them to bed then they get one and they soon learn that human hands are not just out to grab them.
It helped that Sophie called a meeting of the Speckledys yesterday and had a word!!
"Are you actually listening to me?"
"Do you speak 'dog'.....I didn't get a word of that.....Do you think I nodded in the right places?"
