Hi everyone, my chicks are 4 weeks old & today I thought it would be a good idea to give them some treats. I bought some large crickets & they went nuts. my barred rocks especially they each ate 10-15 & swallowed them whole. The other 2 took their time, picked them apart & only ate a few each. I soon noticed one of my barred rocks moving her head from side to side & up & down as if she were trying to force the food down. so I picked her up & felt her throat & there was a pretty big lump on the right side. I could feel the legs & body's of the crickets. It was pretty hard as well. The other barred rock had a similar lump as well. They also got sluggish and kind of just stood there as the other chicks picked around the yard. What should I do?
