I dont try to sell eggs or birds to get rich. I will sell a few eggs when I have extras, and sometimes sell live birds just to help with the feed cost. I keep my birds because I just like messing with them. Usually when I get to many birds or chicks, I just call up the local trader and sell him whatever I want to get rid of. Note, this isnt the best way to make money off your birds. I have had several breeds and am now cross breeding to make mutt chickens I like to look at. I also keep some rare breeds and try to improve on them by selective breeding, but I dont want to get into serious show breeding, I just want birds that look like I think they should. For eating eggs, I could get by with 1/2dz layers, but I probably have close to 100 birds of various ages. I'll let them grow, keep the ones I like and cull the rest. I hatch way to many chicks and enjoy every minute of it.
