Hello, I am new to the community and new to chickens too. We got out first chicks 2 weeks ago. 3 bantums and a brahma. A few days ago we added 4 more, 2 buffs and 2 barred rocks. I noticed last night that one of the buff chicks(she is probably a week old at most) seems to have a large crop. The material in it isn't hard, but it hasn't gotten smaller throughout the day today, also isn't larger either. She is acting normal(eating, drinking, pooping). They are getting chick starter, some grit,and a few meal worms. Tonight I cleaned the brooder and took everything away besides the starter and water. I haven't separated her yet. Any suggestions? THANKS!
