Hello chicken experts! There are a few birds that arrived at a local animal shelter that I'm trying to identify. The picture is pretty grainy because with the lighting and the birds flying about, it was near impossible to get a clear shot in. The birds are classed as chickens. They have fairly curved beaks and are very, VERY flighty. They look to be the size of maybe a 10 week old standard chicken, but some of the feathers are pretty developed--though they are missing a lot of feathers and have bald spots. They seem a little more upright than my hens (RIR, EE). Two have pale legs, one has bright yellow legs. Any ideas? Thanks!!!
