urgent! crop bound?

hi all,
have just been to give corn to my chooks and i notice 2 out of the 3 of them have big lumps on their chests, i had a little feel and it seemed hardish. they are all walking around and seem happy although it is protruding quite a lot. i noticed it straight away.

do i give veg oil now? or wait and see how they are in the morning?

don't want them to get poorly.

think they have been being greedy with the grass today as the snow has melted now!!

advice appreciated, thanks

its normal, they are supposed to look like tennis balls at the end of the day! its the food they have eaten throughout the day. Mine sometimes feel quite hard, and smetime they feel like well stuffed bean bags, you can feel the bits of grit in there. As a generel rule, it should be empty in the morning, although occasionally you will get the odd chicken with a bit left in. If the chickens are behaving normally, i.e bright and alert, interested in whats going on, eating, drinking etc, im sure they are fine. If on the otherhand, they are not eating/drinking, tail down, hunched in a corner, looking very sorry for themselfs, then something could be up. Impacted crop and sour crop are two different things, although sour crop can follow on from an impacted crop. Impacted crop feels ROCK hard, in our case it was caused by long grass/string, sour crop feels like a water balloon, and her breath will smell rancid. This is caused by bacteria, both these conditions will causes the bird to be very unwell. There is loads of advice on here about these problems, do a search, i always thing forwarned is fore armed...fingers crosed for you that it is just the 'normal' end of day full crop.....it is very visable, they look like they have 1 huge boob

lol

now you know how they should be at the end of the day, if they are empty then you need to keep an eye on them.

all part of the learning curve we have all been through keeping chucks.

never be afraid to ask if you are concerned, everyone has been there at some time.
