We are new to chickens this year. We bought 6 Americauna chicks. One died soon after. The seller replaced it with a Rhode Island red. We later bought a sex linked black and sex linked red. Turned out 3 of our Americauna's were roosters. One rooster is very loud and protective of the hens. One is interested only in mating and the other acts like a hen, altho both will crow. So, we have 2 Americauna hens. When they started laying, we got about a dozen green/blue eggs altogether, and then no more. Now we only get shades of brown eggs from the other three. We have a big, roomy hen house and they have access at all times to a large yard. All the chickens appear to be healthy. Don't know why the americauna's started to lay, then quit.
