1) can I give my 7 week old chicks tortilla shells? 2) one of my chicks that I got who was the little one of the bunch still hasn't grown and the chick is now 7 weeks old. The chick stands at about 2 inches maybe 3. The rest are about 2 or 3 times bigger than the little fellow. Should I be worried? 3) I got this shelf with 20 boxes on it so I could cut it into laying boxes. The boxes are 15 inches high, 15 inches deep, and 11 inches wide. Would they be ok with those dimensions? 4) they don't like using the ra,p to get into thier house so I have to manually pick them up and put them into it at night. When I open the lodge in the morning, they will walk out onto the little ledge I built for them and jump off. Could the box be too high off the ground? Or does anyone have any suggestions as to why they wont use the ramp?
