I got an email from Meyer Hatchery saying they have their brown egg layer assortment and their 25 pullet rainbow pack on sale 20% off!! BUT you have to order by 1 EST today and they go out, today! So...I have 24 from a rainbow pack I ordered from them 3 weeks ago...would it be realistic to order more? I'll have the room once the coop is done but, will they be able to "mingle" eventually? Fast responses would be appreciated as their is a time constraint!
