I bought 4 keats in April or May and have no idea yet if they are male and female. One is definitely smaller than the other 3 and 2 are definitely the biggest leaving 1 right in the middle. (If that makes sense) Anyway, my question is, if I have 3 males and only one female, do I have to get rid of the extra 2 males? I hear they are monogamous so it seems like they wouldn't be like roosters and continue to fight over the girl. Will they be one happy family or will there be strife? I should mention that I bought them for tick extermination on our farm. Eggs would be a benefit but not essential. Thanks.
