We bought 8 baby chicks form a local farm feed store. They said they different breeds were Ameraucana, Cornish, ISA Brown, and Rhode Island Reds. We asked for 4 reds and 4 ISA browns. We are raising them for eggs and didnt want cornish. The girl told us the ameraucanas were all gone. Now looking at these chicks I'm wondering if they are Isa or in fact the cornish. Any help would be appreciated. She also was unsure of when they were hatched and said she thought they were a couple weeks old. Do they look that old? Here are some pics.
