Hello fellow chicken-lovers, I'm a new member from Australia who has just adopted 3 Isa Brown chicks. I think they are about 2 weeks old. They are feathered but have tiny tail feathers. They are eating mostly crumble, and a little plain yogurt and bits of green leafy vegetables. We have had an influx of christmas beetles around our house and some have flown into the chicks' brooder and settled into the shavings/litter on the floor. I can tell every time a chick digs one out because they cheep like mad and chase each other around. It's very cute but I'm worried that the chicks may be injured if they actually swallow one of these beetles. The beetles have quite rough legs and tough shells and can pry their way out of my closed fist. I have been letting the chicks have a run around and play with the beetles before removing the beetle from the brooder. Could the chicks be harmed by swallowing them? Also, I haven't bought any grit as yet and I'm not sure if the crumble has any in it. Do they need grit if they are eating bugs? If so, can it wait several hours until tomorrow morning? Thanks and I look forward to your response.
