Meyer is good but yiu have to add shipping to their catalog prices
Welp is good and includes shipping but no small orders, you could donate the extra chicks to me or sell them on CL.
Ideal has great birds and a special leghorn layer. There is a small shipping surcharge if you order less than 100 birds, something around $7 for my area. Last time I checked their min order was $25 dollars after discounts and before shipping. But call the order in if you are not willing to accept roosters as box fillers.
