crickets, roaches and the like? How about a slice of apple or a piece of lettuce?
How old before chicks can eat....
You can start offering treats as soon as they are eating their chick starter really well (usually takes a few days after hatching). Then you can give them whatever you want to, in small amounts, and always sprinkle a bit a chick grit on the new food item. The sooner you start offering treats, the less wary they will be of trying new things to eat as they get older.
I bought my chicks Friday 2 days ago and the guy said their shipments arrived on Fridays, but these were ones that had already been there so I guess they're about a week and a half old. Anyway, I won't be giving any more treats until they're bigger and have a little more room. LOL I tossed a dead roach over in there and I thought they were going to kill each other. After they've calmed down and had a nap, because I KNOW they're worn out, I'll inspect them all for injuries, punched out eyes, etc. It was like the chicken version of "tackle the man with the ball". And it's obvious they know each other because even after one would take it from the other, a couple would keep chasing the one who had lost it until they said, "HEY! So and so has it!" LOL What a hoot.
