Hi, I am not brand new to chickens, but know the basic of chickens. I got 4 different pairs of chicks on end of first week of March 2018. The pairs I got for my 10 years old daughter is 2 different kind of Bantams, Rhode Island Red and Production Red, Welsummers and White Leghorns. I found this website by look up the white leghorn got swell Crop (spell) and she got all better! I am Hard of Hearing and have Hearing Service dog which is American Golden Retriever, work at title and escrow company, and loving my life! Hope to learn more about them.. so exciting! I might need help to identify bantam chicks.. black and white look like Grey Japanese Bantam rooster? Other one possibly look like Partridge Cochin Bantam hen? let me know if I am right about those kind breed.
