Might be early to tell but I think the latter 2 might be Roos... I live in the country so no biggie but the lakenvelder is my daughters chicken and we got it from the feed store out of a pullet bin. Her Wyandotte looks like a pullet to me but I'll add it just to check... It's also a feed store chicken. I'm new to chickens and I'm trying to figure out who is what SLW Rose... My 8 year old says rose is part parrot... I can't wait till rose is full grown and tries to sit on her shoulder! Lol Lakenvelder 4-5 weeks Astrolorp mix? 3 weeks-ish?
