Hello Everyone, I posted a question about one of my pullets last week in a different forum, but never really got any reponses. So, here it is, worded differently. I received my 6 pullets at approximately 9 weeks old. They are now about 12 weeks old. I have 3 RIR, and 3 BR. So far, all have been doing fine, eating well, drinking, pooping, normal chicken stuff. I have become a bit concerned over one of my Barred Rock, named Batgirl. All the other pullets are growing really well, and are getting bigger, except Batgirl. She seems to be really scrawny compared to the others, and doesn't seem to be getting bigger. She is now considerably smaller than the rest, at the same age. She eats fine, is actually kind of aggressive about food, and is drinking and pooping regularly. I am wondering if she might have some kind of problem with her crop, that might be affecting her growth rate and ability to thrive. I have noticed lately, that what I assume to be her crop, always seems to be full. Of course, she is quite thin, so maybe it is more prominant than the other girl's. She doesn't smell or anything strange, and her behavior is fine. Would it hurt to feed her a bit of bread soaked in olive oil, just in case her crop is sluggish? Should I also be putting some ACV in my girl's water? Please, any advice is appreciated. If she is just small for her age, or is runtish,, I'll stop worrying. I just don't want to ignore a potential problem, and her health suffer. Thanks so much!!
