Yesterday I purchased 3 Golden Comets hens from a local farmer. He said they were around 2 years old. At the time they were in a livestock trailer with about 30 other birds. He grabbed them by the feet and carried them out of the trailer. I didn't notice anything obviously wrong with any of them but I was also a little overwhelmed looking at all the birds and being new to chickens. As he carried them out upside down, one had some clear drainage coming from its mouth. I did not notice any color to it but the consistency was similar to a cross between water and mucus (didn't flow out really slow but did not come out quite as fast as just water). He said the chicken must have just taken a drink of water and that's what it was. I know there are probably many worse case scenarios, but was that most likely what it was? There was a clean drinking water pan in the trailer. I may be over reacting but I figured better to ask and be safe than sorry.
