I am going to pick out some chicks which will be hatching in 3-4 weeks. I can wait a couple weeks if I need to (it's a long drive) but once I get there is there any way to tell what colors/varieties/gender individual birds are as 2-week olds? As 4-week olds? The person doing the hatching has said there are "all kinds of varieties" in the mix .Just wondering. I've done some searching on this forum but as always the "sticky" threads are too massive to actually find information in. Thanks, y'all!
