We started feeding them mealy worms, and I haven't started feeding them grit yet. I have some cockatiel grit but I don't know if I should have purchased parakeet grit (size of grit). Also, since they've been getting mealy worms (unfortunately probably too many cause my kids love feeding them to them) I didn't give them any grit, although I did let them scratch in the dirt a over the weekend... but I have noticed they are pooping less than they were just on the chicken starter crumble. I hope I didn't hurt them by not giving them grit yet... the feed store I bought them from said I didn't need it to feed them mealy worms, but this board says different. I shouldn't trust this feed store anyway, they don't seem to know a lot about chickens.. Anyway, should I be feeding parakeet size or cockatiel size grit at this point? The store didn't carry chicken grit..
