Thank you for the suggestions! I have not seen any bullying or fighting over food as they all seem to get along well and always roost together in a clump. Lucy and Ethel are best buds, as are Wilma and Betty. Ethel is the biggest one and I doubt she would let anything happen to Lucy. If Lucy doesn't start putting on some weight I will have to separate her, but I know she will be very upset to be away from the rest of the girls. I am hoping she is just a late bloomer and doesn't have anything going on inside. What ever it is, it can't be contagious since the others are healthy. I probably am just worrying too much LOL
I get how you must feel.
