Okay three of them are suppose to be golden comets but I have no idea how old they are (4 months) and the other one which seems to be having a bit of difficulties in confinement; I was told was an Americana and this chicken is HUGE! So my question is Are three golden comets..indeed golden comets and if so around 4 months???? The fourth bird is it an Americana? Is it a hen or rooster? Any guess on age? Oh and there is some gunk on the eye...is this something?
