i agree with everything said here. Your birds are cornish rock X. They are bred to be rapid growth meat birds. I raised our last batch to 16 weeks before butcher. They weighed anywhere from 10lbs (had cross beak) to 18 pounds. Most being 15 to 18 pound birds. Most people butcher between 8 and 12 weeks but they can be raised to a little older if you watch how big they are getting and watch for leg problems. Ours made 16 weeks cause they were free ranged a lot and were made to search for some of their food which helped to keep them mobile. I would age those birds around 6 weeks by the looks of them.If they were purchased the second week of May they are most likely not nearly 3 months old - *most* chicks sell out from retail stores within the first 1-2 weeks of their arrival (stores will often reduce the price on birds after the first week to move them out and make room for new chicks and because they aren't really set up to brood them long-term). Do you have any photos of them when you first purchased them? Seeing them as they were will help to gauge their approximate age at purchase and their age now (I would put them at 8 weeks at the most, but leaning closer to 6 from the looks of them). Cornish Cross are genearlly processed between 8-10 weeks of age due to their rapid growth and development.
Also, sidenote, the Ameraucana you were sold is actually an Easter Egger - same general idea, but the difference is Ameraucana are a pure breed and Easter Eggers are mixed breed birds that have blue egg laying parentage (Ameraucana, Araucana, Legbar, etc) - these are often misrepresented by hatcheries as being Ameraucana or Araucana. Personally, I prefer the EE, as they tend to be more productive layers than either of the breeds they are sold as being and they come in a wider variety of colors and patterns.
