My one and only silkie has been losing weight so last night I brought her back up to the house. This morning she has a hard crop. I'm new to chickens so I am assuming I missed this early on. (Am really mad at myself) they get starter and some layer crumble(chicks vary in age) along with grit oyster shell and cracked corn and vegtable scraps. What can I do? Please tell me I didn't kill her.
