I have 26 - Three and 1/2 week old chicks. Well I've been trying to get them to go out in the run for days. Nope too scared, a couple would step out a little then the others would peep and they'd run back in FAST. Finally this morning I had alot of time to sit out there and temp them to come out. Finally they did and they loved it. They discovered plants and bugs!Now they'll never want to come in again. Heres the funny thing. A HUGE butterfly swoops in and I swear they thought it was an aerial assault!!! They all took off heads down running for cover. I guess thats one bug they'll have to be bigger to eat. It was 1/2 their size. I'm still laughing.
