both my chicks have the right side of the chest bumped up...and when I feel it, it feels like a muscle...but if they had muscles there, wouldn't they have it on both sides? My thought was could it be that they ate shavings and/or the new start feed (that is more pebbling then the powder food the feedstore was feeding them) and they need grit? I gave them some grit last night after reading that it was ok to do so (they are on day 5..wait 6...hmmm? math this late, not good, they were born on Sat april 18th) Anyhow, if it's an impacted whatever they store their food in (ignorant to formal terms...sorry!) will that grit help in a few days? how would I know if that's it? What can I do to help them? Other then me seeing that bump, they both act very content, sleeping when I come in the room the get up, peep a little, peck at the food and water, then after a little hello....I think they go back to resting, because when I check on them, they are normally resting with the stuffed animals in their brooder...there's only two of them.
