HI, I posted a similar question on the raising chick thread, thought I'd repeat it here as maybe a better place for it: My RIRs are 4 weeks. I'd like to start giving them small amounts of "treats" like fruit, veggies, etc. However - would I need to give them grit? If so, what kind - all the grit I've seen is oyster shells, or at least has some shell in it. Would that be too much calcium for my babies? I read that too much calcium in young chicks can shut down their kidneys. On one bag, it said not to give it before 10 weeks... I've also read on this forum about giving chicks a pan of dirt from the run they will inhabit to get them used to that environment of germs, etc. Is this a good idea, if so at what age? Also, is there anything I shouldn't give them (other than the obvious contaminated food)? I do not have them on medicated feed, but they get Terramycin in their water. At what age should I stop this? And should I just stop, or taper off gradually so their own immune systems have time to gear up? Thanks in advance for any advice.
