Bantam Salmon Faverolles are fantastic birds. Good layers in winter, sweet disposition, gentle roosters. The eggs are nice size for a bantam. If the quality is good 25-30 is not to much to pay for quality birds. If you are not interested in raising them to show or to have show potential eggs to sell, then it may be a bit much to pay. I have very nice Salmon Faverolles and I usually offer them on this board for $20.00 including shipping for 8 to 10 eggs. Depending on the time of year you will have to pay more for eggs due to availability . I usually sell on eggbid and I have gotten anywhere from $15.00 to 20.00 per dozen. I usually charge a flat rate for shipping of $9.00. So your price seems to be in the ballpark.
