I rescued a pullet yesterday, poor girl had not been looked after very well. I put her in my small hospital coop so that i could keep her isolated from my flock. The 1st think i noticed yesterday was that her crop looked big, i checked her this morning and her scrop is not massive but there is a good tennis ball size hard lump, so i am assuming she is impacted, am i right? Also i noticed her poop is very runny and very very green, is that a side effect of the impacted crop? or some thing else going on? I was going to worm her but i'm going to hold back and deal with one thing at a time. I have given her plain water and yogurt for now, is there any thing else i should be doing? I will be grateful for any advise you good people can offer me, i am fairly new to chicken keeping. Thanks in advance, Marlene. PS ment to say that i was told she is about 30 weeks old, but i'm not too sure, anyway to tell a chickens age?
