Wow! 26 Polish! That's pretty awesome--I only got 19 (and 13 of them were Silver Laced Polish). Your chicks look really big for one month! Mine are three weeks now and they still look pretty small, I wonder if I'm not feeding them enough.
Do your chicks run away from you/are frightened by you? All of mine will literally run to the other side of the cage asap when I go inside to change out their water/food. I don't know if this is normal and they become nicer later on? Otherwise, I'm going to have 55 feral, human-hating chickens. A select group (maybe 15 of them) will eat out of my hand if I stay still enough. And there is one chick (who was yellow) but now has tan/white feathers coming out who is always the first to run up to me to let me pet her/him. That is the only one that isn't afraid of me and is always curious when I go in (so he/she's my favorite).
