Hi I am new here and bought four little babies to take care of from the local feed store on Monday. I have two Rhode Island Reds, and two Buff Orpingtons. I forgot to ask the man when they were hatched so I don't know how old they are. I would like to attach pictures, but I don't know how......can someone tell me if there are directions to posting pictures on here or direct me how to do it? Also when is it okay to give them the rock(I forgot what it's called) that they need in order to digest things other than the chick starter. The feed store man told me all that I would need is the chick starter...It seemed like he was having a really bad day, so I didn't ask about anything else. I would like to start feeding them treats, because I saw them yesterday chasing a bug, and I realized that they would start wanting other things besides chick starter. At what age is it okay to give them bugs? and do they need the rock in order to digest it? Sorry for all of the questions!!
