One of my 6 girls just started laying 2 days ago. I had a little starter/grower left about a week ago so I bought layer pellets and mixed it with the last of the starter/grower to get them used to it. The first 2 eggs had shells, they were just very thin. So last night I put up a feeder with oyster shell and showed them where it was. But I was wondering can I also give them yogurt and other things every day since they did not seem to like the oyster? Is there a danger of giving them too much? Also the yolks were very nice and pretty but not very orange and rich. They only get to free range for about an hour each night because we have a hawk so I have to be out there with them and right now I cant stand the heat for longer than that. I do try to give them greens frequently (3 times a week). Spinach, peas, brussel sprouts, etc. Should it be every day? Thanks for any input.
