I have keets that are about 5 weeks old and already in their coop for the past week. They are able to get to the grassy areas and I'm sure they're eating the greenery. I have kale, collards and spinach in my garden. Since they have pretty much destroyed the grassy area they are in is it okay to give them some of these greens? Also, what about grit? I put a little bucket in their coop but I'm not sure if they need it already. The are also on a high protein chick starter. Any information is appreciated! Thanks!
