I have 5 of these. They are very laidback and quiet but I do not know what they are. I am pretty sure these are Light Brahmas Easter Egger Buff Brahma A very tall fast growing chick. I think Wellsummer? This blue chick is chunky built ?? This blue chick is small and birdlike. It feathered out fast. They are all healthy and already living outside in the coop with a heat lamp. I got them in the Leanes Adopt Me Assortment. I am very pleased with the 25 chicks and have not lost any of them.
