help with orps

i brought two buff orps at the weekend , alarm bells should have started ringing because one has a sore eye,which seems blue in colour and  although he said they were about eight months old one is alot bigger than the other ,they both seem perky enough and are eating and drinking.
they dont have any combs is this normal for that age, still glad i brought them they didnt look that well cared for any advise would be appreciated thankyou

yes  there in a different area of the garden so they wont come into contact at all

just another point o add on to Joyfulls reply, orpingtons normally don't grow much of a comb.  They are very small and neat, close to their head.  At eight months, they should be close to laying, but with orpingtons, as with other large breeds, often don't start laying ontil they are a lot older then the lighter breeds

that eye doesn't look too good at all does it. I would take her to a vet, she may be blind in it through being pecked, or she may have an infection in it from again being pecked or from dirt or pooh getting in it. If it is the latter then a course of topical antibiotics should sort it out (although the vet may need to take swabs to get cultivated to see what bacteria is growing in it).
