Chicken food can be bad, so try not to let them eat too much, mine occasionally get out and get some but they can quickly eat too much. I don't think a handful here and there will cause any troubles, they do seem to like the taste of it. A ration made for growing goats is the best.
We will usually band ours at 8 weeks, they are strong and healthy and can take the stress of it. It's not enjoyable to watch but it needs to be done.
Male goats can have troubles with bladder stones, I personally have never had any with them. I think the key is to not feed alfalfa, a good grass mixed hay, second or third cutting is best for goats. Also limit grain, especially as adults. I feed none most of the year, during winter I feed a bit of sweet feed mixed with cracked corn. Goats take two years to fully grow. I will feed a small amount of either sweet feed or a goat ration for the first year. A handful twice a day.
I like getting them as babies, they think I'm their mom and are more interactive that ones others have raised. They will try to suckle constantly, that's just what they do. That's because the mom will only allow nursing occasionally and only for a short time, so they are always ready to nurse. They will eventually grow out of it, but even my adult goats like it when I put my hand around their mouths like when they nursed, they close their eyes and freeze, it's funny. You might change your mind later about raising kids again, once you figure it out it's easy and fun.
