Hi, I purchased 12 baby chicks 3 days ago when they were 1 day old. I chose 2 white rocks, 2 jersey giants, 2 NHR, 2 RIR, and 4 easter eggers. We noticed from day 1 that Rita was a trouble maker. She was trying to look for a way out of the box right away and chirped the loudest and ran after the other chicks. At day 3 (yesterday) Rita was going around biting all of the other chicks toes and feet. Chicks were not even near her, she would just run up to all of them and start pecking their toes. And then started getting very territorial and as soon as she got to a new spot or corner in the box she would scratch her feet on the spot like she was marking her territory. I'm thinking she could possible be a rooster? My other 11 chicks are so delightful and peaceful I hate to see this chick bother the other ones. Can I have some opinions?
