I have 11 6 week old chicks, 5 Isa Browns and 6 Cornish Cross. And they are the biggest babies I've ever seen. Granted, I am new to chickens and they were my first batch, so I spent a LOT of time with them in the craft room, (where 2 of my brooders are set up) I'd just go in and hang my head over the edge of the tote, or let my hand dangle inside it.. They'd come over and peck at the freckles on my arm.. or the little hairs on my arm. They are all super sweet.
I have what I
call the teenagers, because I have 3 different ages. They are 4 weeks old... 5 Silkies, 2 Barred Rock and 2 Silver Laced Wyandotte. THEY are truly flighty. Omgosh, I couldn't even hardly walk over to the brooder and peek in without feathers flying everywhere. I've been making a conscious effort to spend more time with them. Doing the same with them as I did with the first batch. I've even been hand feeding them meal worms...
I have the advantage of them being shut up in the brooder. But from what I've learned so far, chickens are very inquisitive. Try going in to your coop or out in the run with them and sitting on a over turned bucket or on the ground... with some black oil sunflower seeds. I have not tried this myself. Yet. But I plan on it.
Odds are, they will be nosy and want to know what you have. And as soon as they figure out it's something yummy, they'll want to be friends.
Just my .02 but it's worth a shot. Good luck!!
