I would love some advice in regards to my 2 year old RIR mix bantam hen, Spicy. She is lowest in the pecking order in my group, and always tries to roost in the nest box. So, every evening, I go in and put her on the roost next to our roo, Rusty, the only one I know that won't try to knock her off. Tonight, when I went to put her on the roost, I noticed that her breast bone was protruding, and she has very little meat on her. I felt her crop, and it didn't feel very full at all. I tried feeling my other hens for comparison, but they are standard breeds. However, they had nice full crops and I could hardly feel their breast bone at all. She should be going through a molt right now, but if she is, it isn't very noticable. My hens freerange, and have complete access to layer 16% layer feed at all times. I can't say that I have seen her eating out of the feeder, as it is in the coop, but I do see her pecking around at the ground and she does eat the BOSS and cracked corn that I throw out as a treat in the morning. All my chickens, including Spicy, were wormed with Wazine 17 days ago, and wormed with Ivermectine 8 days ago. Any ideas of what could be going on, or how I could fatten her up? Thanks!
