Yes, you're right. I only have a small coop and could not get more than 4 polish. I asked the lady to get me 4 extra chickens when she ordered from Murrey McMurrey. She was going to place an order. And yes, I only want vaccinated chickens. I was under the impression they came from the hatchery and were fully vaccinated. Until I found out otherwise. Yes, some people are unethical.
I really hope you get your Polish again! They look absolutely ador-a-ble! I waffled in the beginning between Silkies or Polish since both are very sweet breeds! I was given two free Partridge Silkies from a homeschool teacher mom who hatched eggs for a classroom project so that's how it was decided I'd have Silkies instead of Polish. Since I open-range the hens during the day I decided not to add Polish to the flock with those huge vision-impairment crests of theirs. I found the Silkies are very aerial-predator conscious and hide well but with raccoons, coyotes, and Coopers Hawks in our area I'm not sure Polish would be as alert to their surroundings. Cute cute cute birds and perhaps one day I'll add a couple in lieu of Silkies to see how they fare in the backyard flock.
