I've got some gold laced polish and orpington eggs coming in from Ideal hatchery next week and I had a few questions before its time to put them in. I always here about marking the eggs with an X and O, but I don't know what to use, would just a regular number 2 pencil be fine or would that leach into the egg or something? Also for my brooder box what time of litter should I use? I plan on putting newspaper over the litter for the first few days but still have no idea what type of litter I need. And has anyone ever bought eggs from Ideal before to calm my nerves? Thanks!
