Another newbie here! We just acquired 6 leghorn chicks last week, I believe them to be about 2+ weeks old (wing feathers and tail feathers are almost in) and today, after hearing me say that chicks like the egg yolks from hardboiled eggs, my son dropped one into their bin. They went crazy for it and by the time I realized what was going on they had already devoured a good bit of it. We have not introduce grit yet. They are in a bin with pine shavings and have water and the medicated chicken feed and that's it. Is that going to be a problem or is the yolk ok for them without grit? If it is a problem, is there something I should do now? Thanks!
